Check Valves

High-pressure rated swing check valve

Backflow prevention and minimal pressure loss in fire protection systems.

The UL/FM/AWWA C508 Swing Check Valve is a resilient seated valve rated at 350 psi — one of the highest in its class. Designed with a full waterway passage, it ensures low-pressure drop even at elevated flow rates. The valve supports inline maintenance without disassembly from the pipeline, making it ideal for critical fire protection and industrial systems. Built to comply with ASME and ANSI standards, it offers flexibility in installation and dependable performance.
