Datasheet
F2 Valve General Features
The Emech 2 port valve utilizes ceramic shear action
disc technology to provide tight shut-o󰀨, high pressure
di󰀨erential capability and long life integrity.
Combined with the Emech digital actuator, high speed stand
alone closed loop control is possible. The Emech 2 port valve
utilizes ceramic shear actions discs as the dynamic seal.
The extremely hard nature of the ceramic produces outstanding
resistance to wear and cavitation damage compared with
conventional elastomer and plastic seated valves, minimizing
seal replacement and plant downtime.

Note:
1. The charted seating and unseating torques are the sum of all friction and resistance for opening
and closing of the disc against the indicated pressure differential for normal service.
2. The relationship between values are linear, and can therefore be interpolated between nominated values.
3. The effect of dynamic torque is not considered in the table.
4. In sizing operators it is not necessary to include safety factors.
5. Break-open torques are approximately equal to the shut-off torques.
The charted values are based on clean liquid service at temperatures between 32°F to 212°F with no internal
deposition or chemical attack, operated a minimum of once a day.*
For conditions that vary from those noted above, apply the following application factors.
Note: The above factors are cumulative but never more than 2x the value shown in the Break Open Torque tables above.

Installation
When installing the valve in line, be sure
to follow good practice using either
sealing tape or thread adhesive in the
joints.
The valve may be attached straight to the
pipework.
NOTE: Be sure to consider the ease of
removing the valve should this become
necessary in the future. See images 3 and
4 below for typical installation methods.
NOTE: For valve maintenance, the bonnet
screws can be removed and full access to the
internal components is possible.
The valve may be connected to the pipe
work with a union style of tting.
The valve may be connected to the pipe
work with a thread adapter and a clamp
style tting. e.g. Tri-Clover™.
CAUTION:
WARNING:
WARNING:
WARNING:
WARNING:
Prior to installation ensure that the pipes leading to the valve are clear from debris which may block or
damage the valve on commissioning.
Only trained personnel familiar with pipe work and pressure systems should install and maintain
Emech equipment. Failure to do so may result in serious personal injury!
Depressurize pipe work to atmospheric pressure and drain all uids from the pipe work before working
on the valve. Failure to do so may result in serious personal injury!
Ensure that the intended maximum operating pressure of the line does not exceed the pressure rating
of the valve. Failure to do so may result in serious personal injury!
The valve must be supported adequately so as not over stress the pipe work and or the valve body.
See Figure 5 and Table 2.1 below for the maximum nozzle loads on the valves. Application of loads above
these values may result in serious personal injury and or equipment damage!

3.0 - Flow Control Valve - Model F2
Maintenance- Dismantling
CAUTION!
Before dismantling the valve,ensure all
upstream and downstream pressurised pipe
work is isolated appropriately.
Ensure the pressure and uids are drained
from the valve and pipe work.
After removing the gland nut locking screw,
unwind the gland nut counterclockwise using
the spanner provided. (Image 1)
Using a hex wrench, remove the four cap
screws around the bonnet. (Image 2)
Carefully remove the bonnet from the body
particularly if the valve is mounted in a
vertical position.
The spindle may detach from the rotating
disc and remain in the bonnet.(Image 3).
Remove the spindle and ensure that the two
thrust washers and needle bearing is on the
spindle. You may have to remove these from
the bonnet.
Alternately the spindle may stay attached to
the rotating disc in which case it should be
carefully removed. (Image 4)
In either situation, the spindle will need
to have two O-rings and two wear rings
removed (Image 5).
Remove the discs from the valve body.
Remove two energizers and check the pins
for any damage. If the pins are damaged
they need to be ordered separately (Image
7).
Finally remove the O-ring around the ange
of the bonnet (Image 8).

Maintenance - Reassembly
Replace the pins if they are damaged.
Before assembling/re-assembling the valve,
make sure hands are free of dirt and grease
and the valve is clean.
Fit the energizers into the body. Apply a light
even coast of grease to all seals. All Emech
seal kits are provided with recommended
lubricant. (See table 4.2 on page 15).
Place the bottom disc onto the valve body.
Apply a light even coat of grease to the top
surface of the bottom disc. (Image 3)
Place the top disc on the bottom disc and bed
it down by rotating one on the other.
Ensuring the disc slots are clear of dust or
dirt, check the spindle ts neatly into the slots
on the top disc.
NOTE: The spindle should be tight tting. If
the spindle does not sit at on top of the disc,
clean lugs. If the spindle still does not sit at,
le the lugs.
Fit the two O-rings and d the top and bottom
wear rings to the spindle.

Align the discs with the spindle on top before
gently lowering the bonnet over the spindle
down to the body (Image 11).
Secure down the bonnet with the allen head
cap screws using an allen wrench (Image
12).
Check the torque of the bolts to the range
indicated in table 4.1. (See table 4.2 page
15).
Apply a light even coat of grease to the
spindle bearing surfaces and the O-rings
(Image 7).
Check the t of the spindle in the bonnet
(Image 8). If the spindle ts, proceed to
Image 9.
Lightly grease both sides of the thrust washer
and place on the spindle. Place on the
needle roller bearing (Image 9) and apply
grease (approx 60% of the void space).
Lightly grease both sides of the second thrust
washer and place on the bearing.
Apply a light even coat of grease to the body/
bonnet seal O-ring and bonnet bore. Place
the O-ring around the perimeter of the bonnet
(Image 1).
Rotate the spindle one full rotation. The
movement should be smooth and even with
no variation in torque (Image 13).
Lubricate inside and outside of the gland
nut, paying particular attention to the thread.
Insert the O-ring in the gland nut and then the

“Zero” Notch
With the gland wench provided, screw
the gland nut down until it bottoms out.
Do not over-tighten! (Image 15).
Back the gland nut o󰀨 3 notches (70
degrees). If the notch does not align with
the locking screw head, back the gland
nut o󰀨 further to align (Image 16).
Insert the locking screw after applying a thread locking adhesive (Image 17). Tighten the
locking screw as per the torque values given in table 4.1.
NOTE: Rotate the spindle 1-2 times to ensure the operating torque is constant, and the
rotating action is smooth.
Reassemble and connect the handle kit or actuator to the valve. When connecting to
an actuator, ensure that the valve and actuator are both in the “zero” or starting position
before mounting together.
NOTE: The valve is CLOSED when the spindle notch points to the “0” mark stamped on
the valve top (see Image 17).

1.0 Preparing the actuator for assembly onto Emech™ valves
Before fitting the actuator to the valve assembly, ensure the actuator is in the zero position. All new or replacement
Emech actuators are shipped in the zero position. To check the actuator position or to re-zero an actuator follow
section 1.1 if a power supply is available or section 1.2 for manual re-zeroing.
1.1 Automatically zeroing the actuator (24Vdc power supply required)
Power on the actuator (a 24Vdc regulated power supply is required). Refer Section 3
of the G1 actuator installation, operation and maintenance manual for electrical installation.
With a temperature sensor connected to Port 1 of the actuator ensure the actuator is in
Temperature Controller mode (hold mode and press down (-) on the actuator keypad
to toggle between Positioner or Temperature mode). Now disconnect the temperature
probe from the actuator. The actuator will move automatically to the ‘zero’ position and
display “E2” on the keypad display.
G1 actuator keypad
1.2 Manually zeroing the actuator
If there is no power available to
‘zero’ the actuator it is possible to
use the actuator’s manual override
handle to adjust the actuator shaft
position.
The actuator ‘zero‘ is achieved
when the coupling keyway is at 45°
to the reference plane as indicated
in images 1 and 2.
2.0 Actuator mounting orientation
To accommodate installation space restrictions the actuator may be mounted to an Emech valve in any one of four
positions. The instructions provided in this document explain how to mount the actuator in the standard orientation for
each type of Emech valve. To mount the actuator in one of the other three off-set orientations (see figure 2.1) follow
the directions outlined in section 2.1.
2.1 Nonstandard mounting orientations
Ensure the valve is in the “0” position by following the
standard mounting instructions for the valve in the
relevant chapter of this document. When it comes to
placing the graduated coupling onto the valve spindle
orientate the coupling so the “0” mark aligns with the
desired off set direction as indicated in figure 2.1.
Continue with the standard mounting instructions.
Ensure the notch (zero indication on bracket) in the
actuator bracket aligns with the coupling “0” when the
actuator is fitted to the valve.
The valve and actuator will operate as per a standard mounting assembly
