GY46X-300 Deluge Valve Flanged End 300 PSI
The GY46X-300 is a diaphragm-style Deluge Valve featuring flanged connection ends. Engineered by Ningjin APC Industries for high-hazard fire protection infrastructure, this quick-opening valve utilizes system water pressure to hold the internal diaphragm closed until it is actuated by a fire detection system (electrical, pneumatic, or manual).
