ACTION:
Full CW = Valve Closed
Full CCW = Valve Open
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).
Wiring
NOTE: The installed actuator model is indicated
by the last two digits of the VEB valve
model number (e.g., VEB-43xxxxCK
has an MEP-4002V actuator) and the
last three digits of the older VEP valve
model number (e.g., VEP-45xxx745 has an
MEP-4002 actuator). For wiring and other
information about tri-state and other
actuators no longer sold mounted on
these valves, see the respective actuator’s
installation guide on the KMC web site.

Actuator
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
valve.
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.
CK/745 Wiring (MEP-4002)
NOTE: Before January 2014, MEP-40x2/48x2
models had 0–10 VDC inputs. They now
have 2–10 VDC inputs. When replacing an
older 0–10 VDC actuator with a 2–10 VDC
actuator, configure the connected controller
or thermostat output to match.
