Product Overview

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).

*Proportional MEP-4002V, MEP-4252V, and MEP-4552V actuators are available premounted on the valve bodies.
**MEP-4x51V/4x52V/4x54V actuators can also operate from 24 VDC in addition to 24 VAC.
***For 1/2" or 3/4" valves, x = 2. For 1" to 2-1/2" valves, x = 5.
NOTE: VEB-46 assemblies are available with
mounted proportional MEP-4002V, MEP-
4252V, and MEP-4552V actuators only.
NOTE: For two-position or tri-state options, select
a VFB-46 series valve body and aach
any quick-mount “V” actuator from the
table above. Specify VFB-46YYYBC (e.g.,
VFB-4605JBC) with YYY the appropriate
size and Cv from the models chart. The
VFB valve body and the quick-mount “V”
actuator must be ordered separately.
