Bermad Model FP400E 3DC - Pressure Control On-Off Deluge Valve

The BERMAD Model FP 400E-3DC is suitable for flow control in firewater systems that include electric fire detection. It opens and closes in response to an electric signal. When open, it reduces the pressure to preserve the system maximum designed flow.

FP400E-3DC - XXX

Features and Benefits

  • Pressure control function – Constant preset downstream pressure
  • Remote reset – Shut-off on remote command
  • One-piece molded elastomeric moving part – No maintenance required
  • Simple design – Cost effective
  • Obstacle-free full bore – Uncompromising reliability
  • Factory pre-assembled trim – Out-of-box quality
  • In-line serviceable – Minimal down time

Typical Applications

  • Fluctuating or over pressure
  • Water/foam fire systems
  • Deluge & spray systems
  • Petrochemical facilities
  • Flammable materials storage
  • Marine environments
  • Gas storage tanks
  • Remote monitor

Optional Features

  • Alarm pressure-switch (code: P or P7)
  • Explosion-proof for hazardous locations (code: 7/8/9)
  • Fail-safe open (energized to close main valve)
  • Seawater service (add FS as prefix to model)
  • Valve Position Single/Double Limit Switches


The BERMAD Model FP 400E-3DC is suitable for systems that include electric fire detection and a piping system with a wide variety of open nozzles. Combining a pressure control feature, the FP 400E-3DC is recommended for systems with high pressure supply source and/or relatively low flow.

In the SET position, the line-pressure supplied to both the main valve’s control chamber [1] and a 2-way Hydraulic Relay Valve (HRV-2) [2] via the priming line [3] and through a Check Valve [4], an Accelerator [5] with priming restriction, and a Solenoid [6], is trapped by the Check Valve, by the closed HRV, and by a closed Manual Emergency Release [7]. The trapped pressure holds the main valve’s diaphragm and plug against the valve seat [8], sealing it drip tight and keeping the system piping dry. The HRV is held closed by the line-pressure, supplied through the Solenoid. Under FIRE condition, an electric signal triggers the Solenoid to open the HRV. Pressure is then released from the main valve control chamber to the downstream, through the open HRV and the Pressure Reducing (PR) Pilot valve [9], allowing the main valve to open, and water to flow into the system piping and to the alarm device. Should system pressure rise above PR pilot setting, the PR pilot throttles, thereby enabling pressure to accumulate in the valve’s control chamber. This causes the FP 400E-3DC to throttle closed, decreasing system pressure to PR pilot setting. The Manual Emergency Release [7], overrides the PR pilot, causing the valve to open fully.

Engineer Specifications

  • The On-Off deluge valve shall be a UL-Listed, solenoid remote controlled elastomeric type globe valve with a rolling-diaphragm.
  • The valve shall have an unobstructed flow path, with no stem guide or supporting ribs.
  • Valve actuation shall be accomplished by a fully peripherally supported, one-piece balanced rolling-diaphragm, vulcanized with a rugged radial seal disk. The diaphragm assembly shall be the only moving part.
  • The valve shall have a removable cover for quick in-line service enabling all necessary inspection and servicing.
  • The control trim materials shall consist of St.St. 316 tubing and fittings, and plated brass accessories, including Accelerator, 3-way Solenoid, HRV hydraulic actuated pilot valve, 2-Way Pressure Reducing Pilot, Y strainer and Manual Emergency Release.
  • The control trim shall be supplied as an assembly, pre-assembled and hydraulically tested at an ISO 9000 and 9001 certified factory.
  • The Pressure Control and Solenoid Remote Controlled, On-Off Deluge Valve shall open and close in response to activation of the solenoid, reducing higher upstream pressure to preset lower downstream pressure.
