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.
