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.
