Mounting
3-Way, Mixing or Diverting, Flanged, Control Ball Valves
VEB-56 Series
Installation Guide
1. Clean the lines upstream from the valve. Remove
any debris (welding slag, pipe scale, or other
contaminants) larger than 1/16 inch (1.6 mm).
NOTE: If the system experiences large amounts
of debris, steps should be taken to keep
the system clean, such as 20 mesh strainer
installed upstream of the valve.
2. Align the valve assembly according to the system
ow requirements (see the illustration below).
3. The valve may be mounted on either vertical or
horizontal pipe lines. On horizontal lines, mount
the valve so the actuator is positioned upright

and over the valve. (Leave sucient room on all
sides to service the actuator and valve.)
CAUTION
To prevent condensation from dripping onto the
actuator housing on horizontal lines, mount the
valve with the actuator in the upright position or, at
most, at a 45° angle.
4. Install approved ange gaskets (not supplied by
KMC Controls) and bolt the valve to the pipes.
5. Eliminate air from the system to keep the valves
full of uid during operation.

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
Wiring is dependent on the type of actuator and
the desired options that are available. Consult the
actuator model label and then the relevant sections
in the MEP-7500/7800 Series Actuators Installation
Guide for detailed instructions on the applicable
wiring, feedback selector, and actuator/signal range
reset (auto-mapping) of the valve’s actuator. (See the
More Information section.)
More Information
For models, specications,
and additional information,
see the VEB-56 Series Data
Sheet on the KMC web site
(www.kmccontrols.com).
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. The motors are
permanently lubricated. Careful installation will also
ensure long term reliability and performance.
