Air operated Pinch Valves with Flange Connection - RVA Series

The air operated pinch valves of the RVA series are available in the nominal diameters of DN25 to DN350. DN400 and DN450 upon request.

They are designed with a flange connection complying with DIN EN 1092 (PN10/16) as standard. On request, the air operated pinch valves of the RVA series can be made with a flange connection complying with ANSI B 16.5- 150lbs, if required.

Structure of RVA series

The RVA series air operated pinch valves consist of the essential part of every pinch valve, the sleeve, and a two-part (half shell) body. The pinch valve sleeve is positioned in the centre of the RVA series air operated pinch valves' body because of both of its flange ends and the geometry of the sleeve. Both of the body halves are sealed pressure tight against each other using a PTFE packing cord.
