CLA-VAL 33A/TDe : Air Release & Vacuum Breaker Valve with Throttling Device
Designed to protect pipelines from air lock and vacuum collapse, the CLA-VAL Model 33A/TDe 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 admits air during pipeline filing or draining. The throttling device restricts air discharge to minimise pressure shocks at pumps start up.
