Fire Protection - Air Release & Check Valves

Cla-Val - Air Release & Vacuum Breaker Valve with Air Throttling Device

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 formations in pipelines. A large venting orifice and large float clearances freely exhaust or admit air during pipeline filling or draining. 

Cla-Val - Air Release Valve

Cla-Val?Series 34 Air Release Valves are designed to vent entrained air that collects at high points in a pipeline. This valve continuously eliminates air from a system by releasing small quantities of air before large air pockets can occur. Stainless steel trim is standard.
