2" Air and Vacuum Valve 300 PSI UL/FM
Cla-Val 2" Threaded Air and Vacuum Valve
Designed to protect pipelines from air lock and vacuum collapse, the CLA-VAL Model 33ATD Air Release and Vacuum Breaker Valve eliminates air and prevents vacuum formation in pipelines. A large venting orifice and large float clearances freely exhaust or admits air during pipeline filling or draining.
During normal pipeline operation, air accumulation and buoyancy cause the floats to lower or lift. As the water level lowers inside the valve, small amounts of accumulated air are released through the small orifice.
Once air is released, the float poppet closes drip tight. Valve servicing is easy because the entire float system can be replaced without removal of the body.
