KMC Controls VEP-43 Series Installation Manual

Mounting
NOTE: To assemble a quick-mount "V" actuator on
a valve body, see the
Guide 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
(mixing or diverting—see below) 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
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.
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).

MIXING Flow Action:
Full CCW = Port A to AB
Full CW = Port B to AB
DIVERTING Flow Action:
Full CCW = Port AB to A
Full CW = Port AB to B
Operation
After the mechanical and electrical installations
have been completed, cycle the actuator to verify
the direction of rotation for normal operation and
fail-safe if so equipped.
Maintenance
No routine maintenance is required. Each compo-
nent is designed for dependable, long-term reliabil-
ity, and performance. Careful installation will also
ensure long-term reliability and performance.
