Reliable shut-off of smooth media flows

Pinch valves VZQA from Festo as a simple alternative

Pinch valves VZQA from Festo come into their own in applications requiring smooth media flows and reliable shut-off. In many applications they are an ideal alternative to conventional valves such as diaphragm or ball valves, as they are particularly durable, energy efficient, easy to service and flexible in use thanks to their open architecture.

Pneumatic pinch valves are a clean, reliable 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 reliability and durability to all kinds of production processes. The VZQA product series from Festo offers modularity, flexibility, durability, ease of cleaning and straightforward servicing.


Reliable flow rate                                                                                      

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


Advantages compared with conventional process valves

The free passage of the pinch valves VZQA minimises flow resistance, continuously preventing the valve becoming blocked or clogged. Since they are operated with a direct air supply, they also offer impressive value for money.


Another plus is their straightforward servicing. The sealing cartridge can be quickly changed in just a few simple steps and without any special tools. The high-performance pinch valves from Festo can be cleaned quickly and easily by machine thanks to their full passage and design with very little dead space.




Performance-packed interior

Made from aluminium or stainless steel, the pinch valves prove themselves in even the most challenging environments. The internal parts offer the same durability against external influences. Whether abrasive, corrosive, highly viscous or neutral influences, the VZQA can withstand very high stresses in daily operation thanks to its special sealing cartridge.


Energy efficiency

The pinch valve VZQA 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.
