Product Details
Swiss VAT Vacuum Butterfly Valve 21.0- Butterfly Valve
Applicable when space occupation requires a replacement solution for gate valves
21.0 butterfly valves can provide the same reliable vacuum isolation as standard gate valves, with the advantage of lower space requirements. The butterfly principle combined with a compact driver design can be successfully installed in situations where space is very limited.
The valve can operate normally under different pressure conditions.
The 21.0 series has been installed in thousands of demanding applications under various process conditions, proving its reliability. The 21.0 series has a sturdy design that reduces maintenance and makes maintenance more convenient, which is convincing in all aspects.
It has been proven that the 21.0 butterfly valve is very suitable as an isolation valve for vacuum pumps.
The 21.0 butterfly valve series is made of stainless steel and comes with ISO-F standard flange connectors for DN 63-160 mm (2 half '-6') types, and ISO-F and ISO-K flange connectors for DN 250mm (10 ') types. Can integrate ports for rough extraction (bypass), exhaust, or metering.
The sealing material for the valve cover and valve plate seals is fluororubber.
