Butterfly & slide valves:
Double chamber valve
Double Chamber Valve series DVC/M, DVC/P and DVCF
The double chamber valve is a device mostly used while granular or powder materials must be brawn out under high vacuum conditions (filters, pneumatic transport...) As a standard rotating cells would be very short due to unavoidable leakages.
This water-proof valve avoids all leakages and, more important, no wear problems are found as no parts require rotating. The valve can be supplied with mechanical or pneumatic motor-driving, in iron alloy or stainless steel version.
