3-Way Latching Universal Relay Valve

The BERMAD URV-3-M Latching Universal Relay Valve is a 3-Way spring
return frictionless balanced poppet type, pressure operated and diaphragm
actuated latching relay pilot valve.
The URV latching relay valve is designed for use with BERMAD deluge water
control and foam concentrate valves, the URV will actuate the BERMAD main valve upon control pressure release from the URV control chamber (the main valve will be “pressure to close”)
Once opened, the URV remains latched in the open position even if control pressure inadvertently returns and can only be reset manually after control pressure has been re-established. Its balanced poppet design provides reliable operation at low control pressures, while the frictionless isolation membrane design greatly enhances reliability and durability. This makes it particularly well suited for use with firewater, brackish water, seawater, and other corrosive fluids.
