The BERMAD URV-3-0 is a 3-way Spring Return Balanced Poppet type, pressure operated diaphragm actuated pilot valve. The URV changes its position from open to close in response to pressure being supplied to its control chamber.
The URV pilot valve is used as a relay device designed for BERMAD Deluge and Remote Control Monitor Valves, commonly used to actuate the BERMAD main valve upon pressure release from the URV (the main valve will be “pressure to close”).
The URV’s balanced-poppet design enables safe reliable operation with a low control pressure using compact dimensions. The URV is specifically designed for Fire Safety systems in that it has no mechanical friction of the internal parts, greatly increasing reliability.
This also makes it ideal for use with corrosive fluids such as firewater, brackish water or seawater.
3-Way control: No continuous release from main valve control trim, suitable for foam systems and pit installations.
Frictionless operation: The isolating membranes eliminate mechanical friction enhancing safety and reliability, well suited for use with sea-water and corrosive fluids.
Balanced Poppet Shaft: Enables a low control pressure, regardless of water line supply pressure.
Heavy duty construction: Suitable for on-shore as well as the severe conditions of offshore facilities.
Corrosion resistant construction materials:
For use with corrosive media and harsh environments
