Area of application:
To be used as a safety element during pneumatic filling of silos.

Layout and operation principle:
During pneumatic filling the bulk material is blown into the silo by means of compressed air. Placed inside the filling line the pinch valve allows the full line cross section to be used during the regular filling process, ensuring high flow rates and low wear and tear. The strong rubber cladding of the valve’s membrane makes for long service life.

In case of an undesired incident (control failure, for example), the pinch valve can quickly be closed by applying pressure to its membrane with compressed air at least 2 bar higher than the pressure of the
material flow.

Material:
Housing: Cast iron, Aluminium
Membrane: Rubber
Control air connection: G 1/4“

Technical data:
Operating pressure: 4 bar
Control pressure: 1,8 - 2,0 bar higher than the respective operating pressure (max. 6 bar)
Connector flange: DIN 2576, PN 10 alternatively internal thread 3“ or 4“

Advantages:
• Fail-safe
• Economic
• Low wear and tear
• Short closing times
