LFPV20CB

Pressure Relief Valve

Lead Free* Models Available

Size(s):

½” and ¾” NPT threaded

Description:

The Model LFPV20CB is a direct sensed direct acting, diaphragm actuated Pressure Relief valve.

It is normally held closed by the force of the adjustable spring setting above the diaphragm. It modulates toward an open position when control pressure, exerting force below the diaphragm, exceeds the spring set-point, and modulates toward a closed position when the control pressure falls below the spring set-point. The LFPV20CB senses upstream pressure through a tapped inlet port. The large diaphragm-to-seat ratio allows it to open and close within close pressure tolerances.

This stand-alone unit is UL and FM approved for Fire applications and can handle inlet pressures up-to 450 psig.
