Information Required to Size the Valve:
• Running water pressure drop*(psi)
• Steam pressure drop** (psi)
• Water temperature rise required (dT) °Fahrenheit.
• Required flow (U.S. gpm
NOTES:
* The ‘Water Pressure Drop’ is the difference between the running water pressure at the wate
inlet port and the outlet port.
** The ‘Steam Pressure Drop’ is the difference between the running steam pressure at the steam
inlet port and the pressure at the outlet port.
To Size the Valve:
1. Determine the cold water capacity of the valve using the “Cold Water Capacity” column with the ‘Water Pressure
Drop’ column.
2. Using the ‘Steam Pressure Drop’ column, locate the steam pressure available at the valve steam inlet port.
Determine the ‘Temperature Rise’ required by subtracting the inlet water temperature from the desired water
temperature desired. Go across the columns to locate the temperature rise required to find the flow (U.S. gp
the F5 can heat to the required temperature..
3. Compare the capacities found in steps 1 and 2. The LOWER of these two capacities is the maximum amount of
hot water that size valve can produce to the desired temperature.
NOTE: A minimum flow rate must be established for there to be effective mixing, and temperature contro

F5025 4 (15) U.S. gpm (lpm)
F5040 6 (23) U.S. gpm (lpm)
F5050 20 (100) U.S. gpm (lpm)
EXAMPLE:
Using the 1” size valve (F5025).
Assume the running water pressure drop is 60 psi (4.0 bar), and the steam pressure drop is 40 psi (2.5 bar). The 1”
(25 mm) valve can pass 72 U.S. gpm (268 lpm) of cold water, but can only heat 14 U.S. gpm (54 lpm) with a 100°F
(50°C) temperature rise.
Therefore the capacity of the mixer for this case is only 14 U.S. gpm (54 lpm).
If the steam pressure could be raised to 100 psi, the capacity of the same unit would be 35 U.S. gpm (152 lpm),
100°F (50°C) temperature rise.
Safety features of the F5 valve when coupled with the Emech® G1 actuator:
• If the cold water supply fails the valve will be closed within approximately two seconds.
• If the temperature sensor fails the valve will be closed within approximately two seconds.
• The G1 has a manual override handle enabling operation of the valve when there is no power supply.

CAUTION: Prior to installation ensure that the pipes leading to the valve are clear from debris which may block or damage
the valve on commissioning.
WARNING: 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!
WARNING: Depressurize pipe work to atmospheric pressure and drain all fluids from the pipe work before working on the
valve. Failure to do so may result in serious personal injury!
WARNING: 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!
WARNING: Non return valves are strongly recommended upstream of the valve inlets. Failure to install them may cause
undesirable back-flow and may result in serious personal injury and or equipment damage
WARNING: The valve must be supported adequately so as not to over stress the pipe work and or the valve body. See
Figure 5 and Table 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!
2.0 - Steam Water Mixing Valve - Model F5
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 pipe work.
Note: Be sure to consider the ease
of removing the valve should this
become necessary in the future. See
images 3 and 4 for typical installation
methods.
Note: For valve maintenance, the
bonnet screws can be removed and
full access to the internal components
is possible.

2.1 Recommended Installation
2.1 - Steam Water Mixing Valve - Model F5
Recommended Installation
Step 1: Location Considerations
For F5 valves mounted with an Emech G1 electronic actuator ensure the installation
locations offers suitable access to the electrical connection terminals, the manual
override handle, actuator power switch, display and keypad.
Do not install the actuator near or in high pressure wash down areas. The units must
NOT be installed upside down. For manually operated F5 valves ensure suitable
access to the handle for safe operation.
Step 2: Recommended Installation
See Figure 2.6 (page 14) for a recommended F5 valve installation schematic.
MUST HAVE
• Check valves (poppet style) MUST be fitted upstream of the valve inlet port
and as close as practicable to the inlets.
• Pipe work adequately supported.
• A 24Vdc regulated power supply.
RECOMMENDED
• Isolation valves are RECOMMENDED on the supply lines.
• A failsafe solenoid operated spring to close isolation valve is highly RECOMMENDED for over
temperature
• failure modes (see item 2 on figure 2.6)
• Ensure mechanical protection of the wiring (e.g. use armour conduit).
• It is RECOMMENDED to place wiring in screened condui or cables.
• Ensure pipe works are straight for as long as practicable to the Emech valve inlets and any cable condit
is fully sealed on both ends against water ingress.
• Use appropriate inlet pipe diameters and supply pressure to cope with required application flows
CONSIDERATIONS
• Consider strainers if water supply carries pipe scale or other particulates that may damage valve seat and
seals.
• Consider gauge points for temperature and pressure on inlets and outlets.
All Emech valves and actuators are shipped fully assembled and factory set to Factory Default Settings
as a standard. Any requirement for customised Settings or Software settings will need to be
communicated at the time of order placement on the Factory.

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

Note: The actuator may be mounted in any
one of four positions.
The instructions below explain how to
mount the actuator facing the outlet port as
per image on page 7.
To ensure the actuator is in the ‘zero’
position, power on the actuator (a 24V DC
regulated power supply is required). Ensure
the actuator is in Temperature Controller
mode - hold mode and press down (-) on
the actuator keypad to toggle between
Temperature and Positioner mode.
Once in temperature mode, disconnect the
temperature probe from the actuator. The
actuator will move automatically to the ‘zero’
position and the keypad display will show
“E2”.
Set the Valve position to closed. Ensure
the notch on the spindle (image 1) points
towards the valve “0” mark and the cold port
(image 2) which is the fully closed position
for the valve seats and the default cold port
(image 2).
Place the graduated coupling (image 3)
on the spindle & ensure the zero points
to the outlet port (image 4).
If the actuator is to be mounted in one
of the other three positions, rotate the graduated
coupling so that the “ZERO”
mark will line up with the notch in the
bracket (image 8) of the actuator,
when valve is fully coupled to actuator.
DO NOT MOVE THE SPINDLE FROM ITS
ZERO POSITION WHEN USING ONE OF THE
OTHER POSITIONS FOR THE ACTUATOR.
Place the center coupling (image 5) on
the graduated coupling (image 6).

Place the actuator on the valve in the
desired position (image 7). The zero mark on
the coupling (image 4) should align with the
notch on the bracket (image B).
Insert one M8 X 25 socket cap screw
into one of the mounting holes with
M8 Spring Washer and Nut. Insert the
remaining three cap screws and fasten.
Ensure the bonded washer (image 0) is on
the sensor (image 10).
Screw the sensor into the outlet port of
the valve (image 11) and tighten before
connecting the the sensor to the actuator.
Plug the sensor connector into the actuator
input port labelled “1” and hand tighten . The
actuator is now assembled
correctly (image 12).
WARNING!! DO NOT USE A WRENCH
TO SCREW THE SENSOR INTO THE
ACTUATOR.
