Diaphragm Actuated Sprinkler Relief valve FP-3PB-0

The BERMAD model FP-3PB-0 is a direct acting, spring loaded, diaphragm type relief valve. The single port is held closed by the force of the adjustable spring located above the pressure sensing diaphragm. When the force of the pressure sensed under the diaphragm exceeds the force of the spring the valve will open to relieve pressure and will close tight when pressure falls below the pre-set value. This FM approved valve is well suited for use in protecting wet pipe Systems, pilot lines and Fusible sprinkler lines from overpressure occurring from temperature fluctuations, pump startup spikes and other.
