VFB-4310DBC | Valve: 2-1/2″ 2W NPT, 72.0 Cv, Quick Mount

VFB-43 series, two-way, NPT, ball valve bodies are designed for the control of hot or chilled water in HVAC applications. Valve bodies range in size from 1/2 to 3 inches and feature an optimizing insert (except for indicated models), which reduces the Cv and characterizes the ball opening for equal percentage flow characteristics. They include a field-repairable blowout-proof stem and leak-proof shut-off. The reduced torque seals and O-rings eliminate the need for high torque actuators.

Order VFB-43 series valve bodies and tri-state or two-way MEP-4xxxV actuators separately. See the actuator chart in the VEB/VFB-43 series data sheet. See also the MEP-4000/4800 series?and MEP-4200/4500/4900 series data sheets for more actuator information.

For complete valve assemblies (with proportional actuators) instead, see the VEB-43 series valves.
