Bermad Model FP720 UL - Pressure Reducing Valve

The Model FP 720-UL Pressure Reducing Valve reduces high, unstable upstream pressure to maintain precise stable downstream pressure, regardless of changing upstream pressure or flow, and requires only existing line pressure to operate.


Features and Benefits

  • Advanced “Y” or angle pattern - Efficient straight through flow
  • Broad operating flow range - V-Port Throttling Plug
  • Advanced pilot system - With integral adjustable closing speed

  • Accurately maintains dynamic and static pressure
  • Double chambered unitized actuator - Protected diaphragm and smooth operation
  • Easy, in-line inspection ensures minimal down time
  • Quick and smooth valve action
  • Replaceable stainless steel valve seat – extended valve life

Optional Features

  • Large control filter (code: F)
  • Seawater service FS as prefix to model

Typical Applications

  • Hose station feeds
  • Sprinkler systems with overpressure
  • Deluge systems with overpressure
  • Foam system
  • Fire hydrant water supply


The BERMAD Model FP 720-UL, pressure reducing valve, pilot operated, automatically and accurately reduces downstream water pressure to a specific, adjustable value. The FP 720-UL operates under both flowing and non-flowing (static) conditions.

The Pressure Reducing Pilot [1] senses downstream pressure [2] and in real time modulates the main valve [3] to maintain a constant downstream pressure.

In no-flow static conditions, should the downstream pressure start rising above pilot setting, the pilot closes, shutting the main valve seal [4] drip-tight to maintain the allowable downstream pressure.

Engineer Specifications

The Pressure Reducing Valve shall be UL Listed for fire protection.

The valve shall prevent downstream overpressure, maintaining a constant pre-determined downstream pressure regardless of varying upstream pressure or flow, incuding static or no-flow conditions.

The main valve shall be a diaphragm actuated, “Y” pattern (or angle) valve. Valve actuation shall be accomplished by one moving assembly containing a double chambered actuator, which shall include a stainless steel stem and a resilient elastomeric seal held by a flat seal disk creating a drip tight seal against the seat.

The valve seat shall be removable and made of stainless steel. The seat bore net area shall be no less than that of the valve nominal diameter and shall have an unobstructed flow path with no stem guide or supporting ribs.

All necessary inspection and servicing shall be possible in-line.

The valve shall be UL-Listed as a pressure controlling water control valve.

The Pressure Reducing Pilot Valve shall be UL-Listed as part of the assembly.

The control trim shall be supplied as an assembly, pre-assembled and hydraulically tested at an ISO 9000 and 9001 certified factory.

Typical Installations

System Components

1 - BERMAD Model FP 720-UL

2 - Pressure Relief Valve (BERMAD Model FP 730-UF)

3 - Isolating Valve

4 - Pressure Gauge

5 - Strainer

Installation Considerations

  • Allow enough room around the valve assembly for any future maintenance
  • Install isolating valves upstream and downstream of the valve system
  • Install the valve horizontally with the cover facing up
  • Install a UL-Listed relief valve (recommended: BERMAD Model FP 730-UF) of the appropriate size on the downstream side of the FP 720-UL, as required by NFPA-20 standard
  • Install a UL-Listed pressure gauge on both sides of the valve

The BERMAD Model FP 720-UL is UL-Listed when installed as a unit.
