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 valve’s position monitoring device features a visual position indicator and can interface with any fire & gas control system. The 400Y-4M is suitable for systems with open nozzles for water or foam discharge.
