leakage Butterfly valve

The AWH leakage valve is used to securely separate media and comes standard with a leakage valve and a rinse valve, also referred to as an auxiliary valve. These auxiliary valves can be actuated  separately or at the same time.

Both valves are designed to be easy to clean and fully isolated when closed. Since the valve piston is virtually flush with the flow tube, this area cannot become soiled. The butterfly valve itself uses our tried and tested hygienic design. The actuator and auxiliary valves can be equipped with sensors to monitor the individual valve positions.

The “double-valve principle” offers the greatest safety when working with different media in the same system. The intermediate flange design makes installation easy during assembly and maintenance. The valve itself comes with our tried and tested AWH standard butterfly valve seals for maximum compatibility with our standard spare parts.

The auxiliary valves come with a 3/8" threaded male connection and can be integrated with ease into the appropriate pipeline system with an AWH weld-on union. A manual variant with mechanical positive auxiliary valve opening is also available from our standard range.
