Festo VZQA pinch valves

Pneumatic pinch valves are a clean and technically straightforward solution for controlling and shutting off a wide range of media. Whether dealing with liquid, fibrous, particulate or granular substances, they bring durability to all kinds of production processes. The VZQA product series from Festo offers modularity, flexibility, durability, ease of cleaning and straightforward servicing.

The pinch valve comes in two versions: an N/O version for media pressures from 0 to 4 bar and an N/C version for media pressures from 0 to 6 bar. A tubular elastomer pinch valve sleeve opens or shuts off the flow by decreasing or increasing operating pressure as appropriate to the version — all without any additional actuators and with no risk of blockage.

The pinch valves can be actuated with low operating pressures. Depending on the medium and media pressure, an operating pressure of just 0.3–1 bar is sufficient in filling and metering applications to tightly shut off the media flow.

The pinch valves come with different connection caps, housing materials and sealing components for a variety of configuration options. This makes them useful for optimising pneumatic delivery and metering systems, powder coating systems and suction and compressed air control units. At the same time, their compact design saves valuable installation space.

The valve’s sealing cartridge can be quickly changed in just a few simple steps and without any special tools. The product can be cleaned quickly and easily.
