PVA Pneumatically Actuated Butterfly Valve

Overview

PVA pneumatically operated diesel engine air intake closure butterfly valves for either hazardous or non-hazardous areas. Suitable for salt air offshore environments.

PVA-280, PVA-350 and PVA-550 valves open on the application of air pressure. The ‘fail safe’ mode of operation of these models makes them suitable for use in zone 1 and 2 hazardous areas.
