1 Important Safety Procedures
Installation, adjustment, putting into service, use, assembly, disas-
sembly and maintenance of the Actuator is strictly reserved to quali-
ed personnel.
Before installation, operation and maintenance, read the relevant
sections of:
- This manual
- Quick Reference Guide: DOC.QRG.XL
Caution: Always disconnect the Air and Electrical supplies before
carrying out any form of maintenance on an Actuator.
Caution: When removing any ball valve or plug valve assemblies
from a pipe system, isolate the piping system on which the Actuator
is installed and relieve any media pressure that may be trapped in
the valve cavities before removing the Actuator for maintenance.
Caution: Always contain the Spring tension with HYTORK Retrac-
tor Rods as explained in Section 9 (Disassembly procedure). Follow
instructions for using the Retractor Rod carefully. Only HYTORK
manufactured or approved Retractor Rods are to be used for Spring
removal. As with any threaded tool that is frequently used Retractor
Rods should be checked to ensure that the threads are not worn or
damaged in any way and greased regularly. Any damaged or worn
Rods must not be used and must be destroyed.
Never attempt to ‘BLOW OUT’ the Pistons or the End caps from the
Actuator Body by using air pressure.
Never turn the stop screws completely out when the actuator is
under pressure
Numbers in brackets (#) refer to parts on the exploded view drawing
(Fig. 5).
All HYTORK XL Spares Kits are supplied with SAFEKEY assemblies
(13/14) cut to an exact length which will t the circumference of the
End Cap (21) when fully assembled into the Actuator. Any shortened
SAFEKEY must not be used. If in doubt contact Emerson Process
Management or your local HYTORK Stocking Distributor.
Read the relevant sections carefully before continuing.
1.1 Warehouse storage
HYTORK Actuators should be stored in a clean, dry warehouse, free
from excessive vibration and rapid temperature changes.
Actuators should not be stored on any oor surface.
1.2 On site storage
HYTORK actuators should be stored in a clean, dry warehouse, free
from excessive vibration and rapid temperature changes.
Prevent moisture or dirt entering the actuator. Plug or seal both air
connection ports.
Important! Failure to follow proper storage guidelines will void war-
ranty
1.3 Lifting instructions
• Use lifting equipement as required by national or local legislation.
• Use lifting straps to lift the assembly of actuator and valve.
• Do not attach lifting straps to only the actuator, to lift the assem-
bly of actuator and valve.

2 ATEX instructions for use in (potential)
explosive areas
2.1 Intended use
The Hytork XL series pneumatic actuators are a Group II category
2 equipment and intended for use in areas in which explosive
atmospheres caused by mixtures of air and gases, vapours, mists or
by air/dusts are likely to occur. Therefore it may be used in (ATEX)
classied Zones 1, 2 (Gasses) and/or 21, 22 (Dust).
2.2 Safety instructions
a Assembly, disassembly and maintenance, is only allowed at the
actuator, when, at the time of the activity, there is not an explo-
sive mixture.
b Prevent entry of explosive mixtures into the actuator. We suggest
utilizing a solenoid with a “breather” function on spring return
actuators when used in potentially explosive atmospheres.
c The plastic position indicator caps are approved for ATEX gas
group IIB areas. In areas where ATEX gas group IIC require-
ments apply, do not use the plastic position indicator cap of sizes
XL426 up to XL4581, to avoid build up of static electricity.
d In order to avoid increasing dust explosion risk, periodically clean
dust deposits from all equipment.
e When equipment is installed in a hazardous area location (po-
tentially explosive atmosphere), prevent sparks by proper tool
selection and avoiding other types of impact energy.
f Proper care must be taken to avoid generation of static electricity
on the non-conductive external surfaces of the equipment (e.g.
rubbing of surfaces, etc.).
g HYTORK XL actuators do not have an inherent ignition source
due to electro-static discharge, but explosion hazard may be
present due to the discharge of static electricity from other valve
assembly components.
– To avoid personal injury or property damage, make sure that
the valve is grounded to the pipeline before placing the valve
assembly into service.
– Use and maintain alternate shaft-to-valve body bonding, such
as a shaft-to-body bonding strap assembly.

Note:
a The actual maximum surface temperature depends not on the
equipment itself, but mainly on operating conditions like e.g. the
temperature of the supply media.
b The specied values are valid with the following conditions:
- Maximum working frequency of the actuator is 1Hz at a maxi-
mum of 50 cycles per hour and at maximum load.
3 Operating Media, Pressures and Temperatures
3.1 Operating media
a Use clean, dry or lubricated air or inert gas.
b Maximum pressure : 8 barg / 116PSI
Note:
On applications where the spring stroke of single acting actuators
is pneumatically operated, the maximum pressure is 6.5 bar /
95PSI
c Dew point 10 K below operating temperature.
d For subzero applications take appropriate measures.
3.2 Operating Temperature range
a Using standard seals and greases the operating temperature
range is -20°C to + 100°C (-4°F to +212°F) as is indicated on the
product label.
b Other medias and temperatures may be used but consult your
local Hytork supplier for conrmation as to suitability.
4 Actuator to Valve Installation
The Pinion drive, coupling device and Valve Stem should be cen-
tered and concentric to prevent any side loading to the Pinion Radial
Bearing and Valve Stem Seat area. Ensure that the coupling shaft to
be operated is a tight but free sliding t into the female drive in the
Actuator Pinion (19).
4.1 Bi-directional Travel Stops
Hytork XL actuators have two travel stops (22, 23 and 24) for setting
acurately the travel and the open and closed positions. XL2586 and
XL4581 can be tted with the optional Bottom Stop Block for setting
the travel.
The actuator has a factory set stroke of 90°. The adjustable stroke
range of the actuator is :
- at closed (0°) position : -3° to +7°
- at open (90°) position : -83° to +93°
REMARK:
- If the actuator is assembled for reverse operation, instead of
standard operation, Stop “1” will adjust the “open” position
and stop “2” the “closed” position.

4.2 Travel Stop Adjustments
1 Operate valve/actuator assembly to the open position.
2 Remove air supply.
3 Slacken locknut (24) on the “closed” stop (marked “2”).
4 Turn the “closed” stop clockwise to reduce or counter clockwise
to increase the travel.
5 Tighten the lock nut.
6 Connect air and check that the position is correct. If not repeat
from 2.
7 Operate valve/actuator assembly to the “closed” position.
8 Remove air supply.
9 Adjust “open” travel stop (marked “1”) as from step 3 to 6.
5 Piping Instructions
(See Fig. 2) All Actuators can be either piped with solid or exible
tubing with the solenoid valve mounted remotely from the actuator or
by mounting a NAMUR designed solenoid valve DIRECTLY onto the
NAMUR mounting pad on the side of the actuator.
6 Solenoid Valves on Spring Return Actuators
(See Fig. 3) It is recommended that on Spring Return Actuators,
the HYTORK “CATS” Solenoid Valves are used. These Valves are
specially designed to prevent contamination of the internals of the
Actuator by dirt from the atmosphere. This increases the working life
of the Actuator which reduces down time and maintenance periods.
7 Position feedback
All position feedback or positioning accesories, that comply to the
VDI/VDE 3845 (NAMUR) standard, can be mounted easily on top of
Hytork XL actuators. To access the pinion top, remove the position
indicator.
8 Spares Recommendations
When disassembling and carrying out maintenance work on the
XL Actuator, a HYTORK Spares Kit must be used to replace all ‘O’
Rings, DURASTRIP Bearings, Washers etc. This Kit is available
from Emerson Process Management or its Stocking Distributors.
9 Disassembly procedure
9.1 End cap and springs dis-assembly on Spring
Return actuators
1 Release Locking Nuts (24) and remove both Travel Stops (22)
and Thread Seals (23) or ‘O’-rings (23a).
2 Remove the Indicator (7) from the top of the Pinion (19) For XL26
to XL221 use an Allen key size 4mm. For the larger sizes the
Indicator can by pulled from the pinion top.
3 Remove both Sealing Bolts (28) and seals (29) from the End
Caps (21).
4 Place both the HYTORK Retractor Rods through the hole in the
End Caps and screw the Rods into :
- For XL 26 to XL 681 the Pistons (20)
- For XL 1127 to XL4581 the Retractor plate (20a, see also Fig
5) until travel is stopped (DO NOT OVERTIGHTEN) and take
care the nut and washer being free of the End Cap face.
5 Turn back the Rod 1/2 turn.
6 Screw the adjusting nut and washer by hand clockwise down
the Retractor Rod until they come up against the face of the End
Cap.
7 Prevent the “hold-nuts “ to rotate by one wrench. Use another
wrench, to screw both adjusting nuts half turn at a time (see Fig.
5) clockwise down the Rods until the end cap loosens (Maximum;
approximately two complete turns). This draws the;
- For XL 26 to XL681 the Pistons (20)
- For XL 1127 to XL4581 the Retractor plate (see also Fig 5) to
the end caps (21) and compresses the springs. This Spring-
compression, releases the Spring force and un-locks the
SAFEKEY for removal.
8 Rotate the Caps to ensure that the Springs are retracted; if the
Cap will not turn easily, a gentle tapping with a plastic hammer
against the endcap will loosen the end cap.
9 Unscrew the two slotted SAFEKEYS (13/14), and gently pull
each SAFEKEY from the Body. If the SAFEKEY resists removal,
gently tap the End Cap with a soft hammer to assist release.
10 When both SAFEKEYS have been removed, use a wrench to
rotate the Pinion, driving the pistons (20) apart until they partially
push the End Caps from the Body.
- For XL 26 to XL681 the Pistons (20), springs and end cap will
come out
- For XL 1127 to XL4581 the Retractor plate, springs and end
cap will come out.

11 To keep the Spring Pack Assembly intact (see Fig. 5), leave the
Retractor Rod in place. To disassemble the Spring Pack, unscrew
the adjusting nut on the Retractor Rod relieving the Spring force,
while preventing the rod from turning with a wrench on the hold
nuts.
9.2 Changing spring sets on XL26 to XL681
12 If only the springs set of the actuator has to be changed, perform
steps 1 to 9. These steps can be performed at both end caps
simultaneously or at one end cap only.
After step 9 unscrew the adjusting nut on the Retractor Rod re-
lieving the Spring force, while preventing the rod from turning with
a wrench on the hold nuts.
9.3 End cap disassembly on double acting actuators
13 Remove the SAFEKEY as described previously. The Retractor
Rod is not required for Double Acting Actuators. Remove the End
Caps by pulling them free from the Body keeping them square to
the end face of the Body.
9.4 Piston disassembly
14 Rotate the Pinion using a wrench to drive the Pistons apart and
remove from the Body by pulling the Pistons.
9.5 Pinion disassembly
15 Remove the snap ring (Circlip) (6), Thrust Washer (25) and
DURASTRIP Thrust Bearing (5) from the top of the Pinion and
CAREFULLY push the Pinion from the Body through the bottom.
Take care that the Pinion does not damage the pinion bores on
removal. If necessary, remove any burrs, etc. from the top of the
Pinion before removal.
16 Carefully remove Pinion Top Bearing (9) from the Body.
9.6 Inspection
17 Clean and examine all parts for damage and wear. Emerson Pro-
cess Management recommends ‘O’ Rings, DURASTRIP Bear-
ings, SAFEKEYS, Washers, etc. are replaced using a HYTORK
XL Spares Kit.
10 Assembly Instructions
Note: The grease used in ALL HYTORK Standard Model Actua-
tors is a Lithium Based Grease. Check with EMERSON PROCESS
MANAGEMENT for high and low temperature applications.
10.1 Pinion assembly
1 Lightly grease all ‘O’ Rings, ‘O’ Ring grooves, bearing grooves
and Pinion.
2 Assemble the Top Pinion Bearing (9) to the Pinion, ensuring that
the recess openings are facing away from the gear form, then
assemble items (8), (17) and (18).
3 Lightly grease the Pinion bores in the Body (11) and insert the
Pinion being careful not to damage the ‘O’ Rings.
4 When the Pinion is in place, install the DURASTRIP Thrust Bear-
ing (5), Thrust Washer (25) and the snap ring (Circlip) (6) into the
narrow groove at the top of the Pinion (ensuring the snap ring ts
properly into the groove).
5 Only open the snap ring (Circlip) enough to just clear the Pinion
diameter as opening too far will damage the snap ring. If damage
occurs replace with a new part.
IMPORTANT: The snap ring (Circlip) has one side with bevelled
edges which must go DOWN onto the Thrust Washer (25); the
square edge side must face UPWARDS.
10.2 Alignment of pinion for correct piston assembly.
Standard rotation is clockwise with the Pistons moving towards each
other (When viewed from above the slot at the top of the Pinion, see
Fig. 6).

(Pistons moving inwards, Fig. 6).
18 Holding the SAFEKEY close to the entry hole (cast identity letter
C or D) to prevent kinking, insert the SAFEKEY into the hole and
gently push into place.
19 With the SAFEKEY Head in contact with the Body, tighten with a
screw driver to gently compress the ‘O’ Ring and create a pres-
sure seal.
20 Repeat the operation for the other End Cap. With the Pistons
together, mount the Position Indicator (7) to the top of the Pinion.
10.6 Spring Return Actuators
10.6.1 Spring set adjustments
The actual selection of the correct spring set can be done by either
referring to the torque charts given in the literature on Spring Return
Actuators or by consulting your local HYTORK representative. After
selecting the appropriate spring set arrange the springs as indicated
bellow.

10.6.2 Installing the Springs.
1 - For XL 1127 to XL4581 place the Retractor plate on top of the
piston.
2 Insert the Springs (26/27) into the face of the Piston and then the
End Cap onto the Springs.
3 Pass the correct HYTORK Retractor Rod through the End Cap
(Fig.6) and screw it into
- For XL 26 to XL681 the Pistons (20)
- For XL 1127 to XL4581 the Retractor plate.
4 Line up the End Cap so that the safety symbol is correctly posi-
tioned for easy reading.
5 Prevent the “hold-nuts “ to rotate by one wrench. Use another
wrench, to screw the adjusting nut on the HYTORK Retractor
Rod in until the End Cap is completely engaged in the Body.
6 It will be necessary to push the End Cap into the Body to over-
come the ‘O’ Ring compression.
7 When the End Caps are in place and the SAFEKEYS tted
correctly, remove the HYTORK Retractor Rods and replace the
Sealing Bolts (28) and seals (29).

6 Align the Pinion by lining up the center of the NAMUR slot in the
top of the Pinion with the single dot on the Body. The top of the
Pinion is marked with a single identication dot to indicate the
correct orientation of the stop faces.
7 Lightly grease all Piston grooves, gear form and Piston ‘O’ Rings
(4) and t the ‘O’ Ring (4) and Wear Ring (3) to the Piston.
8 Fit the Bearing Block (10) to the back of the Piston.
9 Grease the Actuator body bore.
10 Insert the Pistons into the bore, ensuring the piston racks line
up with the pinion gear. (The part number in the front face of the
Piston must be lined up parallel to the Pinion).
11 Push both Pistons together until they are both in contact with the
Pinion, so that when the Pinion is rotated clockwise the Pistons
are drawn together. When the Pistons are together and the racks
are correctly engaged with the Pinion, the top Pinion drive ats
should be at right angles to the axis of the Body.
10.3.2 Counter-Clockwise rotation (Pistons moving inwards,
Fig. 7).
12 Align the NAMUR slot in the top of the Pinion with the two dots
on the Body and assemble the pistons so that the Pinion rotates
anti-clockwise as the Pistons are drawn together.
10.4 Travel stop assembly
(See Fig. 1).
13 With the Pistons together, screw in the CLOSING (cast identity
number 2) Travel Stop (22), complete with Locking Nut (24) and
Thread Seal (23), until it comes into contact with the Pinion stop
face.
14 Rotate the Pinion through 90ø only, driving the Pistons apart and
screw in the OPENING (cast identity number 1) Travel Stop (22),
complete with Locking Nut and Thread Seal, until it comes into
contact with the pinion stop face.
For individual position requirements see chapter 4.
10.5 End cap assembly on double acting actuators.
15 Install the SAFEKEY ‘O’ Ring seals (12) to the SAFEKEY heads
(13).
16 Lightly grease the End Cap ‘O’ rings (2), the End Cap grooves
and the ends of the Body bore.
17 Taking one of the End Caps install its ‘O’ Ring and insert it into
the Body.

11 Testing the HYTORK Actuator
Using compressed air at 80-100 psi (5.5 - 7 bar) check the seal
areas with soapy water, ensuring there are no leaks and that the
Pinion rotates smoothly over its full travel.
11.1 Testing and Cycling of Infrequently Used or Stored
Actuators
Actuators not in current use (i.e. Actuators in storage or stock and/
or not operated for at least a 3 month period), should be cycled a
minimum of ten times and tested against the possible ‘pre-set’ of
the seals. This is a safety precaution recommended by the Seal
manufacturers.
12 Retractor Rods
12.1 Spring Removal System Board.
HYTORK’S “SPRING REMOVAL SYSTEM BOARD” contains a full
set of Retractor Rods so that any size of Actuator can be disas-
sembled on site.
Standard spare parts kits for XL26 to 221 contain the required Re-
tractor Rods. For XL281 to XL4581 seperate Retractor Rod kits are
available. These Rods are not included in the spare parts kits but are
seperately available.
Ask your local HYTORK representative or Stocking Distributor of
HYTORK Products for details.
IMPORTANT:
