Air operated pinch valves

The valve solution for isolating and regulating/metering abrasive, corrosive and fibrous products such as granulates, powder, pellets, dust and liquids containing solids, etc.

Advantages:
Free flow of product, minimum frictional resistance, 100% leak free, no blockages and low net weight are among the most important benefits of pneumatic Pinch Valves. A flattened and elliptical casing design of all flanged pinch valves ensures minimum compressed air consumption. This results in energy savings and ensures a specified, lipped fold pattern to the sleeve of the pneumatic pinch valve.

This specific, lipped fold pattern ensures the complete sealing of the product flow. Even large solids are enclosed by the sleeve in the pneumatic Pinch Valve and are thus tightly sealed.

The different connection options are:
- Flange connection according to
DIN EN 1092-1 PN 10/16 or
ANSI B 16.5/150lbs
- Internal thread connection according
to DIN EN ISO 228 (G) or ANSI/ASME
B1.20.1 (NPT)
- Tri-clamp connection according to
DIN 32676
- Weld-on ends according to DIN 11850
series 2
- Threaded spigot (RJT connection)
according to DIN 11851

Alternatively, aseptic pipe connections, aseptic flange connections or aseptic clamp connections can be welded on according to DIN 11864 and DIN 11853.

Areas of application/customer branches:
Pneumatic Pinch Valves are used in a variety of pneumatic conveying systems, such as the silos/cement sector, pigment and granulate handling, the ceramics/glass/plastics industries, waste water treatment, pharmaceuticals and foodstuffs industry, and winemaking. In addition, pneumatic Pinch Valves are used in metering and weighing systems, powder coating systems, vacuum toilet systems, vacuum conveying systems and vacuum and compressed air control units.
