Air Release & Vacuum Break Valve

Cla-Val air release valves and Cla-Val vacuum break valves are designed to protect against airlock and vacuum collapse in industrial fire protection system components on offshore platforms. Leecyn Company offers these valves in the full range of sizes and configurations, and in specialty and exotic materials and alloys—including nickel-aluminum-bronze, super duplex stainless steel, and titanium—that resist corrosion in seawater environments.

Patented Designs and Proven Performance

Cla-Val air release valves and Cla-Val vacuum break valves employ simple, yet effective, patented designs that automatically eliminate air pockets and prevent vacuum formations in pipelines. Large venting orifices and large float clearance exhaust and admit air, as needed, during pipeline filling and draining.

Engineered for long working lives and minimal maintenance, Cla-Val vacuum break valves and Cla-Val air release valves are easy to install and service. The entire poppet system can be replaced without removing the valve body from the pipeline.

Poured and cast in Newport Beach, California, every Cla-Val air release valve and Cla-Val vacuum break valve is 100% made in the USA. Please see individual product listings for additional information.
