NOTE: To assemble a quick-mount
“V” actuator on a valve
body, see the
on the
KMC web site.
1. Clean the lines upstream from the
valve. Remove any debris larger
than 0.06" (0.015 mm).
2. Align the valve’s flow indicator
with the system flow.
3. Mount the valve so the actuator is
positioned over the valve body.
CAUTION
To prevent condensation from dripping
onto the actuator housing, mount the
valve with the actuator in the upright
position or, at most, at a 45° angle.
4. Seal valves with approved pipe
sealant.
5. Using two wrenches, secure the
valve to the pipe. Torque should
not exceed 75 ft-lb. (102 N
•
m).
6. Eliminate air from the system to
keep the valves full of fluid during operation.
NOTE: If the system experiences large amounts of
debris, steps should be taken to keep the
system clean.

ACTION:
Full CW = Valve Closed (System Off)
Full CCW = Valve Open (System On)
CAUTION
Using mineral oil lubricants or other incompatible
substances in system fluids may damage EPDM
rubber seals in valves. Before using any lubricant or
additive in a water or ethylene glycol base, consult
the substance manufacturer for compatibility with
EPDM (Ethylene Propylene Diene Monomer).
