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.
