Reliable shut off and smooth flow

Reliable shut off and smooth flow

Festo has launched a new pneumatic pinch valve - the VZQA - which provides reliable control and shut off in food and drink production processes. The valves are durable, energy efficient, easy to service, and flexible, thanks to their simple construction, and as a result provide a cost effective alternative to conventional valves such as diaphragm and ball valves.

Festo's VZQA pinch valves are a clean and technically straightforward solution for use with a wide range of media such as liquid, fibrous, particulates or granular substances. They provide smooth media flow and as such they are ideal for optimising filling and metering systems as well as for use with suction and compressed gas controls. In all applications their compact design saves valuable installation space, which enables engineers to enhance the design of their process.

There are two versions of the pinch valve available: a normally open (N/O) version for media pressures from 0-4 bar and a unique, normally closed (N/C) version for media pressures from 0-6 bar.
