Designed with flexible swing disc structure, the valve stays fully open smoothly when water flows forward, bringing little flow resistance and keeping normal water conveying efficiency unchanged. Once backflow occurs due to pressure fluctuation in pipes, the disc will close automatically in a short time relying on its own weight and water pressure. It can effectively block reverse water flow, keep pipeline pressure stable and prevent abnormal operation of fire water supply systems.
PN16 Grooved End Swing Check Valve Fire Safety Check Valve
The grooved swing check valve is designed for reliable backflow prevention in fire protection and water supply systems. Featuring a durable ductile iron body and a spring-assisted swing disc, it ensures fast closure, reduced water hammer, and low pressure loss. The grooved connection allows quick and easy installation without welding. Ideal for fire pump lines, sprinkler systems, and industrial pipelines, it delivers stable and efficient performance.

CA-FIRE Grooved End Swing Check Valve
This swing check valve comes with standard grooved ends to realize fast pipe connection. There is no need for on-site welding or complex hole drilling during installation. Cooperated with matching grooved accessories, it can be mounted rapidly on water pipelines. It cuts down construction time greatly and lowers overall installation expense. The tight connecting structure also guarantees good sealing effect, which works well for both newly built pipe networks and old pipeline upgrading works.
Stable Swing Mechanism to Block Reverse Flow
Solid Material Build for Long Term Service
Made of high toughness ductile iron through integral casting, the valve body boasts strong compression resistance and mechanical stability to cope with regular high-pressure water delivery conditions. Outer surface is finished with red epoxy coating for rust and moisture proof. Internal elastic sealing parts adopt high quality EPDM material, which stands up to long-time water impact and daily corrosion. It hardly gets deformed or leaked even used in damp underground and outdoor environments.
Wide Usable Range Meeting Fire Control Needs
Produced following mainstream fire safety manufacturing norms, this valve features stable pressure resistance and quiet opening-closing performance. It is widely applicable in fire sprinkler pipelines, building fire water supply lines and general industrial water delivery systems. Various common sizes are available for matching different pipe fittings, perfectly fitting construction projects of residential buildings, shopping malls, workshops and other public places.
