This pilot valve integrates all the principal functions of a two-way control circuit into a single assembly. It is a direct acting valve, actuated by a pressure responsive diaphragm, which tends to reach equilibrium with the set spring force. When used in a pressure relief/sustaining circuit, the pilot modulates to open as upstream pressure rises above set point. … read more
This pilot valve integrates all the principal functions of a two-way control circuit in a single assembly. It is a direct acting valve, actuated by a pressure responsive diaphragm, which tends to reach equilibrium with the set spring force. The pilot opens as upstream pressure rises above the set point. An integral restriction acts as … read more
The PORV-A is a direct acting on/off valve, actuated by a pressure responsive diaphragm, which tends to reach equilibrium with the set spring force. The PORV-A is held closed by pneumatic or hydraulic pressure, sensed at its control chamber (under the diaphragm). It opens in response to a pressure drop of the wet/dry pilot line … read more
The BERMAD HRV-2 is a pressure operated relay pilot valve used for release and opening of BERMAD deluge valves. It is held closed by water or air pressure applied to it’s control chamber. Release of pressure from the control chamber opens the HRV-2 relay valve.
The HRV-3 is used to relay and accelerate hydraulic signals, making the opening and closing of large size valves significantly quicker. In response to pressure status in its control chamber, the HRV-3 directs flow and pressure between its ports in the following manner: In response to pressure applied to its control chamber, the HRV-3 connects … read more
The BERMAD model 400Y-7DM utilizes an elastomeric deluge valve, designed specifically for advanced fire protection systems and the latest industry standards. Electric-Pneumatic Double interlock systems include automatic sprinklers attached to a supervised dry sprinkler piping system and a supplementary electric detection system. The 400Y-7DM admits water into the sprinkler system piping only when both the electric detection device and … read more
This Bourdon Pressure Gauge with a polycarbonate (PC) casing provides a visual indication of water or air pressure for BERMAD water control valves, such as Deluge, Preaction, Pressure Control and Remote Control Valves. The core of the Pressure Gauge is a spring suspended movement, which is resistant to reasonable levels of shock, providing long lasting performance. The Polycarbonate casing … read more
This Stainless Steel Bourdon Tube Pressure Gauge provides a visual pressure level indication of lquid or pneumatic media of a corrosive nature. Suited for BERMAD fire protection valves that are intended to be installed in harsh conditions such as chemical or petro-chemical plants, power plants, mining, offshore and onshore. The core of the Pressure Gauge is a spring … read more
The Model PS-10, adjustable, pre-set Pressure Switch is suitable for pressure and/or flow detection in BERMAD valve systems such as Deluge or Pre-action, or with other control valves and is suited for non-hazardous locations. The model PS-10 is also used to provide a low pressure supervisory signal for BERMAD Pre-action Systems and pneumatically controlled deluge valves.
The PS-12 Pressure Switch is for use in conjunction with BERMAD Deluge or other types of water control valves, to indicate discharge water pressure. This Pressure Switch offers reliability, repeatability and durability in a compact design. It is ideal for operation under the harsh conditions of DIV.1 or Zone 1 (II 2 G/D Ex d IIC T6 Certified) hazardous … read more
The Water Motor Alarm is a hydromechanical automatic sound warning device actuated by water flow. It sounds a continuous alarm while a Deluge or Water Control Valve operates. This unit is designed for wall or pipe mounting and is suitable for outdoor installation. The Water Motor Alarm gong assembly package is supplied loose and includes a ¾” strainer.
The BERMAD AMD-75 (Air Maintenance Device) is a pressure control unit that automatically regulates the supplied air pressure to a constant preset value. It is suited for use with dry pilot actuated Deluge systems as well as Dry Pipe and Pre-action systems. The AMD includes a field-adjustable pressure regulator, through which the air/nitrogen supply can be reduced to … read more
