The BERMAD Model FP 730-UF pilot operated relief valve prevents overpressure, maintaining a constant preset system pressure regardless of fluctuating conditions. It is UL-Listed (up to 350 psi) and FM-Approved in accordance with NFPA-20. The valve offers reliable performance when installed in: Refineries, petrochemical complexes, tank farms, high-rise buildings, aviation and airports, marine and on-shore installations.
Note: Optional features can be mixed and matched. Contact us for more information.
The BERMAD Model FP 730-UF remains closed as long as the sensed inlet pressure is lower than the adjustable set point. When the Pressure Relief Pilot  senses inlet pressure  that is higher than the pilot setting, it opens releasing water pressure from the control chamber  causing the main valve to modulate open, relieveing excess pressure to either a reservoir or sump, preventing system overpressure.
The Pressure Relief Pilot is equipped with an adjusting screw  to preset the desired inlet pressure and an integral adjustable needle valve  to control the main valve closing speed. The valve’s unique design and quick reaction to system demand keeps pressure loss at a minimum. To further enhance reliability the control system is equipped with a control strainer .
The Pressure Relief Valve shall be UL-Listed, FM-Approved and hydraulic pilot controlled. The main valve shall be an angle or “Y” pattern. All necessary inspection and servicing of the main valve shall be possible in-line.
Valve actuation shall be accomplished by a double chambered actuator, which shall include a stainless steel stem and a flat seal disk creating a drip tight seal.
The valve seat shall be made of stainless steel and have an unobstructed flow path, with no stem guide or supporting ribs.
The pilot system shall be field adjustable, with adjustable valve closing speed, integrated to the pilot valve, hydraulically tested and supplied as an assembly consisting of:
The control trim shall be supplied as an assembly, pre-assembled and hydraulically tested at an ISO 9000 and 9001 certified factory.
