Product Overview

Features
◆ Mixing or diverting applications
◆ Choice of fail-safe (with switch-selectable
direction) or non-fail-safe operation
◆ Proportional input (or, if valve body and actuator
are ordered separately, tri-state/two-position)
◆ Equal percentage ow characteristics with
optimizer insert (except indicated models)
◆ Cv ratings similar to globe valves
◆ Standard “T” paern connections
◆ Field-repairable valve design

Description
VEB-46 series, three-way, mixing or diverting, NPT,
control ball valves are designed for the control of hot
or chilled water in HVAC applications. Valves range
in size from 1/2 to 2-1/2 inches and most feature an
optimizing insert, which reduces and characterizes
the ball opening for lower Cv ratings similar to globe
valves.
The body design also provides a standard “T”
paern to simplify installation. They include a eld-
repairable blowout-proof stem and leak-proof shut-
o. The reduced torque seals and O-rings eliminate
the need for high torque actuators. KMC’s low-
torque MEP-4xxxV actuators work on all valve sizes.
Valve assemblies have brackets with a patent-
pending, quick-mounting mechanism that creates
a universal connection to VSI, Griswold, and other
valve bodies. Complete valve assemblies are avail-
able with MEP-4002V/4252V/4552V actuators. Order
other actuators and valve bodies separately. See the
MEP-4000/4800 Series and MEP-4200/4500/4900 Se-
ries data sheets for more actuator information.
