AKO have been the forefront of the Pinch Valve design for over 30 years, specialising in a huge range of different industries including powder applications. The company has earned a reputation for designing, manufacturing and distributing pinch valves that are highly reliable, are of a strong robust design and in many cases are completely maintenance free. The only part that needs replacing is the rubber hose inside the body but if used correctly, the durable elastomer hoses can last a very long time.

If you are looking for a cost-effective solution for eliminating flow control problems handling dry, powdered or granulated materials, pinch valves for powders are the answer to all your worries. The secret of their effectiveness lies in the rubber sleeve, which is the only wetted part of the valve. The valve is activated through hydraulic or air pressure that is directly put on the elastomer sleeve. Its body acts as an actuator, due to which you don’t need any expensive pneumatic, electric, or hydraulic operators. Because air operated valves for powders have great rugged flexibility, it enables the valve to close in a “drop tight” way around trapped solid particles.

Valves for powders benefits

The most prominent benefit of AKO valves for powders is their full bore design, which allows for complete shut off. They are capable of providing this effect for solids such as pellets, granules, silvers, fibres, the different kinds of slurries, chippings, in particular powders, and many other aggressive products used in industries. The complete shut off happens because the elastic rubber hose of these valves absorbs the solid particles’ kinetic energy without undergoing any wear, which also helps in resisting abrasion. Moreover, their full bore design also eliminates flow resistance of fluids.

There are several qualities of rubber for these valves including butyl, neoprene, viton, nitrile, EPDM, and natural rubber. In addition, different flange materials and housings such as stainless steel, plastics, and aluminium are also available. Due to this versatility, AKO valves for powders are a preferred choice in many industries over other types of valves.
