NOTICE
RISK OF EQUIPMENT DAMAGE
•
Do not install in open systems using substantial make-up water.
• Follow proper water treatment practices and system
procedures.
Failure to follow these instructio
damage.
These valves must be piped according to the water flow
diagram. Two-Way valve flow should go A to AB. Three-way
valves should be applied only as mixing valves (see diagram).
Best Practice Guidelines
It is recommended to fit a strainer upstream of the valve to
increase reliability and to follow water treatment guidelines as
detailed in VDI 2035.
Recommendations
The pipework system should be flushed prior to the operation.
Mounting
The valves can be mounted in horizontal or vertical piping.
When installed in horizontal piping, the actuator must be above
the valve body. It can be tilted left or right but it must not be
tilted below 90° from vertical.
Installation Notes
• It is the responsibility of the installer or product specifier
to verify media compatibility of the valves construction
materials with the supplier of water treatment/heat transfer
solution.
• Confirm there is no overhead water source that may drip
onto valve actuator.
• In normal service, some condensation may occur on or
around the valve. A drip pan may be necessary or the
valve body may be insulated.
• Do not cover the actuator or obstruct the manual operator
lever.
• Reference product label and Product Datasheet F-27895
for additional product specifications.
ns may cause equipment
Installing the Actuator on the Valve Body for
M22xxxx Unit
1. Turn the valve stem so that the slot on the top of the stem is
pointing towards the large keyed post.
2. Insert the allen wrench into the manual crank shaft on
the top of the actuator. Crank eight turns in the direction
indicated on the label. In the last turn, align the indicator
notch to the opening in the crankshaft. Press the button
around manual crankshaft to lock in place. Remove and
replace allen wrench in cover slot.
3. Align the valve body with the actuator to ensure the stem
lines up with the large stem hole and the large keyed post
lines up with the post hole on the bottom of the actuator.
4. Press the valve and actuator together to assemble.
5. The first time the valve is operated electrically, the manual
operating lever of the actuator will move to the automatic
position. The manual operating lever can be used to allow
flushing of the system after installation.
Removing the Actuator

RISK OF EQUIPMENT DAMAGE
Do not use the valve body to manually open the actuator.

1.
Press and hold the valve release lever inward, towards the
valve.
2. Lift the actuator from the valve.
Checkout
Make sure the valve stem rotates freely before and after
installing the actuator. If the stem does not operate freely it
may indicate that the stem was damaged and may require
that the valve be replaced. After the piping is under pressure,
check the valve body and the connections for leaks. After the
valve and actuator are installed, power the actuator and check
the operation by varying the control signal. On spring return
models, the valve should return to its normal position when
power is removed.
will result in damage to
Installing the Valve Body
1. Apply PTFE tape to the male pipe thread.
2. Hand screw the pipe into the valve, turning it as far as it will
go.
3. Use a wrench to fully tighten the valve to the pipe. Do not
over tighten or strip the threads.
Installing the Actuator on the Valve Body for
M21xxxx Unit
1. Turn the valve stem so the slot on top of the stem is pointing
towards the large keyed post.
2. Align the valve body with the actuator to ensure the stem
lines up with the large stem hole and the large keyed post
lines up with the post hole on the bottom of the actuator.
3. Press the valve and actuator together to assemble.

Theory of Operation
When powered, the actuator moves to the desired position,
winding the spring return system. When power is removed
the spring returns the actuator to the normal position. This
series of two-position spring return valve assemblies can be
purchased with an optional built-in auxiliary SPDT end switch
for interfacing or signaling; for example, zone pump burner
control. The auxiliary switch is designed for contact closure
after the valve is more than 50% open. Do not exceed the
published switch electrical ratings. The manual override lever
is designed to manually position the actuator to install on the
valve or to manually position the valve. Turning the allen wrench
in the manual crankshaft while power is applied or in the
opposite direction as shown on the label will cause permanent
damage. Use only the allen wrench provided with a maximum
torque of 10 in-lb.

Wiring
Make all connections according to job wiring diagrams and in
compliance with local and national electrical codes. Refer to
diagrams shown for typical wiring.
NOTE:
• Multiple actuators may be connected to a single controller.
• Do not exceed the maximum current draw of the controller.
• Use of a properly sized, inherently limited, Class 2
transformer is recommended.
• Use only 18…24 AWG copper wire for all
connectors.
Maintenance
The ball valve assembly itself requires no maintenance.
The stem and packing design eliminates the need for
packing adjustment for the life of the valve. However, regular
maintenance of the total heating and cooling system is
recommended to ensure sustained optimum performance.
