VEB-46/VEP-43 Series 3-Way, NPT, Control Ball Valves (1⁄2 to 21⁄2") 1 Installation Guide
Mounting
NOTE: To assemble a quick-mount “V” actuator on
a valve body, see the HPO-5074 Installation
Guide on the KMC web site.
Installation Guide
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).

1. Clean the lines upstream from the valve. Remove
any debris larger than 0.06" (0.015 mm).
2. Alignthevalve’sowindicatorwiththesystem
(mixing or diverting—seebelow)ow.
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uidduringoperation.
NOTE: If the system experiences large amounts of
debris, steps should be taken to keep the
system clean.
DIVERTING Flow Action:
Full CCW = Port AB to A
Full CW = Port AB to B
MIXING Flow Action:
Full CCW = Port A to AB
Full CW = Port B to AB

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.

Wiring
NOTE: The installed actuator model is indicated
by the last two digits of the VEB valve
model number (e.g., VEB-46xxxxCK
has an MEP-4002V actuator) and the
last three digits of the older VEP valve
model number (e.g., VEP-43xxx745 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.
