The VZQA pinch valves are a clean and technically straightforward solution for use with media such as liquid, fibrous, particulates or granular substances. They provide a smooth flow and are suited for optimising filling and metering systems as well as for use with suction and compressed gas controls.
There are two versions of the pinch valve available: a normally open version for media pressures from 0 to 4bar and a normally closed version for media pressures from 0 to 6bar. However, depending on the medium and media pressure, an operating pressure of 0.3 to 1bar is sufficient in filling and metering applications to shut off the media flow.
The valves can operate in challenging environments and the internal parts offer durability against aggressive media. They can withstand high demands in continuous daily operation, whether abrasive, corrosive, highly viscous or neutral media is used.
