Bermad Model FP400E 3D - El. Controlled On-Off Deluge Valve

The BERMAD Model FP 400E-3D is suitable for systems that include electric fire detection. The Deluge Valve opens and closes drip tight in response to an electric signal.

FP400E-3D - XXX

Features and Benefits

  • 3-way solenoid valve ־ Flexible configuration
  • 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

  • Water/foam fire systems
  • Deluge & spray systems
  • Petrochemical facilities
  • Flammable materials storage
  • Marine enviroments
  • Gas storage tanks

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-3D is suitable for systems that include electric fire detection and a piping system with a wide variety of open nozzles.

In the SET position, the line-pressure, which is supplied to both the main valve’s control chamber [1] and a Hydraulic Relay Valve (HRV-2) [2], through the priming line [3], a Check Valve [4], an Accelerator [5] with priming restriction and a 3-Way Solenoid [6], is trapped by the Check Valve, by the closed HRV-2, 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-2 is held closed by the line-pressure through the solenoid.

Under FIRE or TEST conditions, an electric detection system working through a control panel, triggers the solenoid to open the HRV-2, causing water to exit through the Accelerator faster than it can be supplied. Pressure is then released from the main valve control chamber by the opened HRV-2 or the Manual Emergency Release, allowing the main valve to open and water to flow into the system piping and to the alarm device (if mounted).
