Pressure Regulating Flanged Control Valves VRW Series

Pressure Regulating Flanged Control Valves

 

The Honeywell VRW Series pressure-regulated control valves reduce overall installation labor by integrating flow control and temperature control functions into a single valve assembly and then automatically controlling the flow in each hydronic system circuit to maintain temperature when piping pressures fluctuate. The valves feature an integrated pressure control cartridge that delivers flow balancing and control functions in one package. VRW valves are flanged, sizes 2 1/2" to 6" FNPT, and use standard Honeywell 44 in-lb fail-safe and non-fail safe direct-coupled actuators.
