Pneumatic conveying is a technology used to transport all types of bulk goods around pipeline systems, under positive or negative pressure, and also by vacuum. Sucking or blowing (usually by a flow of air or gas) are the methods used to transport the bulk goods.

When looking for a valve to control the flow in a pneumatic conveying system, a few things should come into consideration such as size of pipeline, distance to convey, and transfer sustance bulk density.

Pinch Valves handle even the most abrasive & aggressive media

Pinch Valves are the ideal solution for use as a control valve or shut-off valve in pneumatic conveyor technology. The Pinch Valve really comes into it’s own within these systems, and can be used in dense phase, semi-dense phase, slug flow, dilute phase, plug flow and extension flow conveying without any issues.

Due to the robust design of the Pinch Valve, and the internal rubber sleeve being an anti-abrasion component, the valve handles complicated and aggressive media with ease. The simple, self-cleaning on-off function of the sleeve opening & closing in the same way every time makes the operation of the Pinch Valve effortless.

The rubber sleeve is the only wearable part of a Pinch Valve and in many cases it can last years. The sleeve can be easily replaced on site by engineers with the help of AKO’s fitting and maintenance instructions and re-sleeve videos.
