AKO Armaturen has introduced the VMC series of air-operated pinch valves, which are designed to shut off and regulate solids of all types, suspensions, pastes, gaseous, fibrous and viscous media.

These valves are based on a multi-functional modular system, which enables flexible exchange of the two types of body available, aluminium (AlSi10Mg) or stainless steel (1.4408), as well as a wide range of different collar caps/flange types in stainless steel 1.4404 and plasticPOM.

It has connection options for internal thread connection, flange connection, threaded spigot, weld-on ends and tri-clamp connection; while aseptic pipe connections, aseptic flange connections or aseptic clamp connections can be welded on according to DIN 11864 and DIN 11853.

VMC air-operated pinch valves are suitable for use in the food, pharmaceuticals, ceramics, glass, plastics and chemicals industries; air-operated pump systems; pigment/granulate treatment; suction/metering systems; filling and weighing units; and ventilation systems.

How does an AKO pinch valve work?

Pinch valves work by the controlling the medium of air pressure or water being used between the pinch valve body and the sleeve to give 100 per cent closure of the pinch valve. Exhausting the pressure causes the pinch valve to open. When open, the sleeve is a true bore allowing unobstructed medium to flow through. The maximum operating pressure is dependent on the nominal diameter and is around 2–6 bar.

All products from the AKO portfolio have received the certificate according to DIN ISO 9001:2008. AKO has demonstrated its high quality worldwide for many years.
