The BERMAD Model 400Y-5D is an elastomeric, hydraulic line pressure operated deluge valve, designed specifically for advanced fire protection systems and the latest industry standards. The 400Y-5D is activated by a hydraulic relay valve, by which opening and closing of the valve can be controlled remotely. The 400Y-5D is suited to systems with remote or elevated wet pilot lines. The valve’s position monitoring device features a visual position indicator and can interface with any fire & gas control system.
