Description
The valve is a high flow, quick opening valve specially designed for fire protection use. It operates using a differential pressure piston mechanism. The container pressure is used with the valve to create a positive force on the piston, thus sealing the valve. The valve opens when pressure is relieved from the upper chamber and the piston move upwards, thus allowing the IG-541 gas to flow out through the pilot line. The upper chamber pressure is relieved via an actuator
