The BERMAD model 400Y-4D is an elastomeric, hydraulic line operated deluge valve, designed specifically
for advanced fire protection systems and the latest industry standards.
The 400Y-4D is controlled by a pneumatic relay valve, typically activated by a decrease in pressure of a pneumatic
pilot line. The 400Y-4D can also be operated remotely.
The optional valve position indicator can include a limit switch suitable for Fire & Gas monitoring systems.
The Bermad 400Y 4D is ideal for use in systems with open nozzles for water or foam discharge also well suited for use with corrosive media or where freezing temperatures might be experienced.
