Quick Release Valve

The quick release total discharge valve operates via a differential pressure system. Each valve is equipped with an integrated pneumatic release device, but can be fitted with an electrical release or manual release device as well. When the release device is activated, the pilot valve integrated within the assembly opens and the upper pressure chamber is ventilated. This pressure drop causes the pressure in the extinguishing agent cylinder to push the closing piston into an open position, opening the valve. The quick release total discharge valve remains open after activation, until the entire extinguishing agent cylinder is empty. The extinguishing cylinder is filled via valve outlet.
