1" Lead-Free Brass Swing Check Valve – Rugged Performance for Flow Control and Backflow Prevention

Engineered for durability and system integrity, the 1" Brass Swing Check Valve delivers reliable backflow prevention for water systems requiring consistent, one-way flow. Its solid brass body and precision-fit swing mechanism make it an essential component for residential and commercial plumbing installations.

This valve is rated for 200 PSI and can withstand fluid temperatures up to 350°F, making it well-suited for both cold and hot water systems. Designed for use in horizontal pipe runs (and vertical runs with upward flow), it provides a dependable seal under pressure and prevents reverse flow that could damage equipment or contaminate clean water supplies.
