Introduction
Section 1: Introduction
1.1 General Application
Actuators are designed for "ON-OFF" or modulating control of any quarter-turn ball,
buttery, rotary plug or damper style valve application.
1.2 Technical Data
1.3 Installation
The actuator can be mounted parallel or perpendicular to pipeline. The actuator can
be installed in any convenient position including vertical, horizontal or upside down.
A. Bolt mounting bracket to actuator hand tight. Do not tighten yet.
B. Install coupling on valve. Be sure rotary stops on valve are removed or adjusted
to allow actuator stops to do the stopping.
C. Install actuator and bracket to valve being sure to leave all fastener connections
hand tight. If possible, stroke valve and actuator to a half open position 45° and
physically shift actuator back and forth until coupling and all fasteners are relaxed
then tighten all bolts and nuts. This procedure will accurately align valve stem to
actuator output shaft and prolong valve stem seal life. Lift the actuator at a balance
point near the center housing. Do not lift the weight of the valve, see Figure 1.
D. Cycle valve / actuator assembly and observe for smooth operation.
E. Adjust travel stops for perfect alignment in both open and closed positions.
NOTICE
If jackscrew override is installed, please refer to Section 3 for stroke adjustment.
F. Tubing connections - some models utilize two pistons for added power.
Spring-return (single acting) dual cylinders designs require one "jumper" to make
the supply port common on both pistons. Double-acting (air to air) dual cylinder
designs require two "jumpers". See Figure 2 for typical arrangement.
! CAUTION
Use correct length mounting bolts! Mounting bolts used in actuator mounting pad may
interfere with the actuator rotary mechanism. Select bolts that will not extend more than
two threads above the back of the mounting pad.
Supply Pressure 40 - 160 psig (2.75 - 11 barg), see product nameplate
Supply Medium any pneumatic uid compatible with materials of construction
Temperature Rating Standard Range: -20 °F to +210 °F (-28 °C to +99 °C)
Optional Range: -65 °F to +300 °F (-54 °C to +149 °C)
Angular Rotation 90 degrees ± 8 degrees

Section 2: Maintenance
Actuators are factory lubricated and in general do not require periodic lubrication or
maintenance while in service. Actuators should be visually inspected periodically for
corrosion damage and promptly repaired. Actuators should be operated at least annually
to assure proper operation.

Jackscrew Override
Section 3: Jackscrew Override
The jackscrew option is intended for infrequent or emergency on-site operation of the
automated valve.
3.1 Jackscrew Operating Instructions
1. Disengage power supply and vent air from actuator.
2. Operate the handwheel to drive the actuator into the desired position. Valve
position can be veried by checking the actuator position indicator. For models
006 through 270, the jackscrew must be returned to the fully retracted position
before actuator can resume normal operation. Back the jackscrew out until it
stops. Air will leak from the jackscrew unless it has been fully retracted against
its internal seal.
3.2 Actuator Stroke Adjustment
The jackscrew has a built-in actuator stroke adjustment, see Figure 3 and 4.
3.3 Models 006 through 270
See Figure 3:
1. Retract the jackscrew override completely by rotating counter clockwise.
2. Loosen the lock nut and turn the brass adjusting screw to the desired position.
The handwheel will rotate with the adjusting screw. Never make stroke
adjustments by turning the handwheel only.
3. Tighten lock nut.

2. Loosen the stroke adjusting screw and lock nut.
3. Using the handwheel, turn the jackscrew to adjust the actuator to the
desired position.
4. Screw the adjusting screw until it stops and tighten lock nut.

Hydraulic Override
See Figure 5.
A. Maintain uid level to ll line using ISO-22 hydraulic uid. Use Chevron
"Hydraulic Oil AW" or equal.
B. The selector control valve is set in center position for remote operation. Select
left or right positions for manual open or manual close as shown on pump label.
C. Store and lock handle to keep pump plunger closed. Do not remotely operate
actuator with handle on plunger.
Figure 5 Hydraulic Override
Manual Handpump Specications:
1. Maximum reservoir ll volume = 75 in3 (1.23 dm3)
2. Pump relief pressure = 1500 psi (103 bar)
3. Pump volume/stroke = 0.66 in3 (0.01 dm3)
4. Handle length = 24 in. (610 mm)

Manual Handpump Hydraulic Override
5.1 Hydraulic Fluid Level
The uid level in the handpump reservoir changes when the actuator is operated. The
uid level is high when the hydraulic cylinder piston rod is retracted into the hydraulic
cylinder. The uid level is low when the hydraulic cylinder piston rod is extended out
of the hydraulic cylinder. Measure the uid level in the low position, using a dip stick,
and maintain this level as shown on the sticker (1 in. [25.4 mm] above the pump base).
Operate the actuator open and closed and view the uid level to verify where the low
position is. Be sure to tighten the ll port plug securely.
! CAUTION
Do not exceed this uid level or uid may squirt out of the relief valve.
5.2 Remote Mounting the Handpump
The handpump is normally installed on the actuator with the ll port on top. When
installed on a valve in a pipeline, the ll port must remain on top regardless of the angle
of the valve in the pipeline. This may require the handpump to be reinstalled in the eld.
The handpump can be remote mounted on an adjacent structure. The optimum position
is close to and above the actuator. If the handpump is located below the actuator, both
speed control valves must be completely closed before removing the reservoir ll plug
to check the uid level. This will prevent hydraulic uid from draining out of the actuator.
Reset both speed controls after the ll plug is reinstalled.

Switch Mounting
(Only with Prox Prep Factory Ordered Option)
A. Remove plastic plugs from proximity ports located on the back of the
actuator housing.
B. Insert switch and turn clockwise until switch touches ferrous activator on yoke,
then back off approximately 1/16 in. (1.6 mm).
C. Test switch by stroking actuator and verifying make and break of switch.
D. Repeat procedure for second switch if required.

Spring Conversion to change Operating Pressure
Section 7: Spring Conversion to change
Operating Pressure
All spring packs except the 40 psi (2.8 bar) consist of an inner and outer spring. The 40 psi
(2.8 bar) spring pack uses an outer spring only. Various spring packages are available
upon request from the factory.
! CAUTION
Before attempting spring conversions always be sure that spring is in the "failed" or
extended position. Remove any accessory equipment that may cause the spring to
be cocked (e.g.: declutchable override, jackscrew override, etc.).
A. Back off adjustable travel stop on end of actuator opposite spring end.
This will allow maximum spring extension inside the actuator.
(Models S003 and B-006 only)
B. Remove tie rod bolts (41). Back off piston bolt (33) until spring is fully relaxed
and piston (25) is free.
C. Remove 80 psi (5.5 bar) spring package and replace with desired spring package.
D. Re-assemble piston, cylinder, endcap and tie rods, being sure to follow the tie rod
tightening sequence (Figure 6A). Do not over tighten bolts. Refer to Assembly
Torque Requirements Chart (Table 2).
(All models except S-003 and B-006)
A. Alternately and uniformly remove bolts (51) from hollow tie rods. Back off each
bolt approximately 1/4 in. (6.4 mm), following the tie rod sequence (Figure 6A).
Repeat the sequence until spring(s) is/are totally relaxed and endcap is free.
B. Remove 80 psi (5.5 bar) spring package and replace with desired spring package.
C. Re-assembly endcap with bolts (51). Use reverse procedure as shown in step B,
being sure to follow the tie rod tightening sequence (Figure 6A). Be sure each
hollow tie rod slides into the counterbore in endcap. Do not over tighten bolts.
Refer to Assembly Torque Requirement Chart (Table 2).
D. Remove nameplate from actuator and stamp or etch correct spring pressure
rating accordingly.

Failure Mode Change
Section 8: Failure Mode Change -
Spring-Return
(Models 003-100) Symmetric Yoke Actuators Only
Conversion from "fail close" to "fail open" is accomplished by ipping the actuator over
(i.e. left to right). The top and bottom of the center housing have identical mounting
anges and output shaft dimensions. Remove the vinyl pointer and indicator plate and
mount them on opposite side of actuator.
(Models 023-7114) Canted and Symmetric Yoke Actuators (Except Noted Above)
Conversion requires removal of the spring cylinder assembly and reinstallation on the
other side of the housing. It is recommended that fail open and fail closed be ordered
from the factory.
