Swing Check Valve

0 Reviews

A swing check valve is a safety device that allows water to flow in only one direction, automatically closing to prevent backflow that could damage pumps or contaminate a water supply.

Detailed Description

Swing check valves are critical "one-way" components in fire suppression piping.

Operation: It uses a swinging "clapper" or disc. When water flows forward, the pressure pushes the disc open. If the flow stops or reverses, gravity and back-pressure swing the disc shut against its seat.
Design: These valves typically feature a flanged end (the circular plates with holes) for secure bolting into a piping system. The top has a removable access cover (bolted lid) that allows for easy inspection and maintenance of the internal swinging disc without removing the entire valve from the line.
Construction: They are usually made from heavy-duty ductile iron or cast iron and finished with a high-visibility red epoxy coating to resist corrosion and identify them as part of a fire safety system.
Performance: They are engineered for high-pressure environments, often rated for 300 PSI or more. Most are UL Listed and FM Approved, ensuring they meet international fire safety standards like NFPA 13.
Usage: Commonly installed at fire department connections, pump discharge lines, and between different water sources to prevent cross-contamination or reverse pressure.
