Features
VZQA-C-M22C function
The pinch valve is a 2/2-way valve for controlling material flows. It is closed in
normal position. The shut-off element is a tubular pinch valve sleeve made
from elastomer. The sleeve opens when the valve is pressurised, releasing the
material flow. When pressure is no longer applied, a spring will close the

VZQA-C-M22U function
The pinch valve is a 2/2-way valve for controlling material flows. It is open in
normal position. The shut-off element is a tubular pinch valve sleeve made
from elastomer. The sleeve closes when the valve is pressurised, completely
shutting off the material flow. When pressure is no longer applied, the
normally closed valve will open due to the inherent stress of the pinch valve

normally open valve. The valve can be used with liquid and gaseous media.
The free passage when the valve is opened ensures minimum flow resistance
and prevents the valve becoming blocked or clogged.

and dusty media, solids (granulate) and mixtures of substances. The free

Application Design
The valve can be used to control
liquid and dusty media, solids and
material mixtures.
Areas of application
The pinch valve may only be used in systems where a damaged or leaking seal
cartridge cannot pose a hazard to people or property. The media circuit must
be sized for the set pilot pressure. The designer and operator of the system
are responsible for ensuring the product is suitable for the system as well as

for ensuring that the seal cartridge material is resistant to the medium used.
Appropriate tests are generally required to assess the suitability. The risks
associated with a leaking seal cartridge and the corresponding consequences
must be taken into account when planning the system.

-H- Note
The hermetic separation between the media circuit and control circuit is no
longer guaranteed if wear causes the pinch valve sleeve to leak. The flow
medium can then get into the control circuit, from where it can escape. Any
potential hazard (e.g. due to aggressive or hot media) must be ruled out. The
compressed air supply to the control valve must be protected against the
ingress of the flow medium using a suitable check valve, or a suitable protec
tion against return flow must be integrated in the pilot line in the immediate
vicinity of the media valve. Pilot medium can get into the media circuit if the
pinch valve sleeve fails. The media circuit must therefore be sized for the set
pilot pressure. Any potential hazard must be ruled out.
