Piston valve

pneumatically-operated

Leakage Butterfly Valve with pneum. Auxiliary Valves and Actuator VMove 1 AWH butterfly valve technology has produced another innovation: the leakage butterfly valve with pneumatic auxiliary valves. It is designed for reliable separation of media and comes with auxiliary valves one leakage and one flushing valve fitted as standard. The auxiliary valves can be activated synchronously or in isolation. Thanks to their design, both valves are easy to clean and completely isolated when closed. Since the auxiliary vales sealing piston is positioned almost flush in the through-flow pipe, contamination is not possible at this point. The butterfly valve itself follows our tried and tested, hygienic design principle. The drive and auxiliary valves can be fitted with optional initiators to monitor the individual valve positions. The "double-flap principle" offers maximum safety when handling different media in the same pipe system.
