Pneumatically Controlled Deluge Valve with Local Reset FP-400Y-4M

The BERMAD model 400Y-4M is an elastomeric, hydraulic line pressure operated deluge valve, designed specifically for advanced fire protection systems, and the latest industry standards. The 400Y-4M is activated by a pneumatic relay valve which latches the main valve open until locally reset. The optional valve position indicator can include a limit switch ideal for Fire & Gas monitoring systems. The 400Y-4M is suitable for systems with open nozzles for water or foam discharge.

Typical Product Applications

Typical Applications

  • Fusible plug loops
  • Automatic water spray systems
  • Foam applications
  • Corrosive water supplies
  • Freezing Environments


System Installation
