Pinch Valves  Manufacturers, Traders, Suppliers

Mass-produced WAMGROUP Pinch Valves are characterised by high material and manufacturing quality.
Pinch Valves
VM - VMM
Industrial quality design
VM/VMM-type Pinch Valves are used for interception of material flow in pneumatic conveying systems, or other pipelines. In addition, they can be installed as a locking device for silo filling pipes.

The body of the VM/VMM Pinch Valve is manufactured from aluminium alloy while the sleeves come in fabric-reinforced material. The sleeve support bushes are either made from aluminium alloy, hardened carbon steel, or 304/316 stainless steel.

HOmatic pinch valves are characterized by the following distinctive advantages:

• innovative, space-saving housing with a modern design

• energy savings of up to 40%
• low mechanical loads on the sleeve
• longer service life

• standard lightweight housing made of aluminium and/or POM plastic
• special series with housing made of stainless steel
• in general full flow cross-section in accordance with the DN rated width
• straight valve passage without constrictions or back-up points

• no clearance volume
• no clogging or blockage
• negligible pressure or friction losses

parts in contact with medium made of POM plastic or stainless steel, with the exception of the sleeve
from rated size DN 50, only the elastomer is still in the medium flow

• question of resistance reduced to a single point

Safety component for the pneumatic filling of silos
Areas 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.
Advantages:

• safe to operate
• economical
• robust
• short closing times
