Pinch
Valves
Safety component for
the pneumatic filling of silosAreas
of application:
The pinch valve is used with the pneumatic filling of silos.
The valve closes by using air/fluid supplied to valve body. The
specially designed sleeve will then close 100 %. Max. operating pressure:
2 to 6 bar (depending on valve diameter).
Function:
Whena filling a silo pneumatically the bulk material is blown with
air pressure through the filling tube into the silo. The plain pipe
profile guarantees high conveying performance and low wear.
In an emergency, the alarm of a security unit or a breakdown of the
control unit etc. the pinch valve will be closed from without by the
increase of pressure on the membrane.
The increase of pressure on the membrane in the spherical part of the
housing at least has to be 2 bar higher than the conveying pressure and
therefore the pinch valve will be compressed to total closeness.
The directly connected solenoid valve allows a quick streaming in of the
control air, which closes the membrane in a safe way.
