"Y" Control Strainer
The “Y” Strainer with a stainless steel or Monel screen is used in all BERMAD Water Control Valves, including Deluge Valves, Preaction Valves, Pressure Control Valves, Monitor Valves and Remote Control Valves. The “Y” Strainer is located at the pressure supply or priming line to protect the control trim components from suspended particles or debris.
2-Way Solenoid Valve
This solenoid valve is a 2-way pilot operated diaphragm plunger type, requiring a minimum differential pressure to operate properly. It has an internal pilot and a bleed orifice, which enables it to use line pressure for operation. The solenoid valve’s design allows for a small overall dimension and a high flow-capacity, which provides a long-life in normal non-corrosive conditions. The solenoids coil is continuous duty design, with an Epoxy molded construction. This 2-way solenoid valve is suitable for activating BERMAD Deluge valves, Preaction Valves and other Hydraulic Control Valves
3-Way Solenoid Valve - Isolating Membrane type
This solenoid valve is an isolated type with an Elastomeric membrane that hermetically isolates the solenoid actuator from the fluid, making it less sensitive to abrasive or contaminated fluids thus providing a safe, and long-life operation. The unique pivoted armature switching mechanism does not require a minimum operating pressure and is unaffected by its mounting position. The solenoids coil is continuous duty design and is encapsulated in a compact Epoxy construction that is suited for corrosive environments. The 3-way solenoid valve, Isolating Membrane type is suitable for activating BERMAD Deluge or other water Control Valves using freshwater, corrosive, contaminated fluids or air.
EExd 3-Way Solenoid Valve - Flameproof Type
This EExd solenoid valve is equipped with a heavy-duty enclosure of Flame proof design. It is suitable for use in hazardous locations, where hazardous materials are present intermittently and defined by zones 1 or zone 2, Group II apparatus category according to ATEX 94/9/EC Directive. This solenoid construction is designed for outdoor industrial applications, the solenoid enclosure and construction are designed to withstand an internal explosion and prevent the transmission of the explosion to the explosive environment surrounding the enclosure. The solenoids coil is IP66 (minimum) ingress protection rated, continuous duty design with class F insulation. This solenoid valve is suitable for activating BERMAD Deluge and other hydraulically controlled valves, used with filtered firewater or pneumatic supply.
Latching 3-Way Solenoid Valve
The Latching solenoid valves are normally de-energized and are activated to operate the BERMAD valve by an electrical pulse, latching it in the release position. Magna-Latch solenoid valve consists of two coils that are incorporated in one enclosure. It is activated to release the control pressure by means of a short electrical impulse signal to the “Pull” coil, the solenoid actuator is then latched in the energized position by a permanent Holding Magnet. To Reset the system, an electrical pulse should be applied to the De-latch coil, creating a counter-force which overcomes the magnet and allows the actuator to return to its normal position. The Magna-Latch Solenoid valve is typically used to enable safe remote control of the BERMAD Deluge valve and other water control valves, by latching the valve in its open position for safe discharge of firewater. Mechanical-Latch solenoid valve (Electrically tripped), is activated to release the control pressure by means of an electrical pulse to the coil, when the solenoid actuator is de-energized, the solenoid valve will remain latched in the release position. Mechanical - Latch type is equipped with a manual reset lever to enable local Reset (De-Latch) to return it to normal position, while the coil is de-energized. Latching solenoid valves are also used in areas where the system runs on limited power supply. They require only 50ms pulse duration to operate with minimal electric current to reduce demand of the power supply, enabling the batteries power capacity to be reduced and increase system reliability.
