Pinch Valves

Air operated Pinch Valve
Manual and control Pinch Valve

Pinch Valves are the ideal solution for isolating and regulating abrasive, corrosive and fibrous products. The Pinch Valve is being used more and more as an isolating valve or regulating valve for emulsions, sludges, dusts, gaseous materials, compressed air, powder, granulates, pellets etc.

There are two types/models of AKO Pinch Valves available:

Air operated Pinch Valves are supplied directly with compressed air/fluid

Manual and control Pinch Valves are actuated under force from a mechanism and actuator


Pinch Valve Characteristics:

Pinch Valves are characterized by a free flow of product, guaranteed because of the nominal passage of practically all diameters. Advantages of include minimum frictional resistance and non-clogging.

Further advantages may be found in its lightweight and compact construction, meaning that they are easy to install. This is something that is appreciated by our customers.

The particularly robust, elastic fabric-reinforced Pinch Valve sleeve allows for successful working, even under extreme conditions. The AKO Pinch Valve sleeves prove their worth, particularly because of their long service life. For instance, if very abrasive media is being conveyed with a very high switching cycle frequency. A selection of 10 different elastomer grades and different body/flange/socket materials ensures that they may be used practically without restriction in almost all industrial sectors. Due to its simple structure, AKO's air operated pinch valve represents a particularly low cost/economic shut-off valve solution, because a separate drive is not required for actuating them. In fact, only a 3/2-way solenoid valve or pilot valve is needed to control them.

The highly-elastic, air operated pinch valve sleeve shuts off the product flow with a 2-3bar differential pressure supply (depending on elastomer quality) and then moves back to the open position without being driven because of its great rebound resilience, once the pinch valve body has been bleed.

Due to its very simple structure they are extremely easy to maintain, they can be repaired or serviced directly on site at the customer's with the aid of installation instructions.
