The BERMAD model 400Y-5M is an elastomeric, hydraulic, line pressure operated deluge valve, designed specifically for advanced fire protection systems and the latest industry standards.
The 400Y-5M is activated by a pressure operated relay valve, which latches the main valve open until locally
The 400Y-5M is ideal for systems with remote or elevated wet pilot lines, due to its boosted local pressure release. The optional valve position indicator can include a limit switch suitable for Fire & Gas monitoring systems.

A typical installation of the BERMAD model 400Y-5M features automatic actuation via a pressure operated relay valve, triggered by a wet pilot line with closed fusible plugs elevated above the deluge valve.
When open and fitted with a limit switch, the valve sends a feedback signal to the remote valve position monitoring system.
