Abrasion-resistant valves are used mainly in industrial systems with problematic and very abrasive media. In these areas of application, it is particularly important to install robust valve solutions to prevent constant maintenance work. Numerous industries must convey abrasive pump media reliably and affordably.
In addition to conventional pipeline systems in processing industries, abrasion-resistant valves are also used in silos, weighing and metering systems and commercial vehicles, especially where abrasive solids and contaminated liquids have to be transported and/or piloted through transporting equipment.
The following industries (excerpt) rely on the reliable and economical functioning of abrasion-resistant valves:
The video shows the structure and function of an abrasion-resistant valve. The installed anti-abrasive sleeve is designed for reliably stopping high-abrasion transported materials.
Especially in the area of the transport and regulation of abrasive solids, a particularly robust mixture of natural rubber in an abrasion-resistant valve is generally used. This mixture also guarantees a long service life even in case of problematic bulk materials. In addition to this very resistant rubber mixture, fabric elements that also increase the life time of the sleeve are worked in as well. In the process, the quality of the materials used for manufacturing determine the anti-abrasion behaviour of the sleeve and therefore its life time.
The service life of abrasion-resistant valves is determined by the respective transported materials and by the quality and/or anti-abrasion behaviour of the sleeves, which function inside the housings of the valves. The higher the quality and abrasion resistance of the sleeve, the shorter the downtimes and the lower the servicing costs for the valve since the maintenance and/or exchange intervals extend and the production downtimes therefore reduce.
Especially in the case of abrasion-resistant valves, the best sleeve must be exchanged at some point This is entirely possible without long system downtimes. Thanks to the simple, but effective construction of a pinch valve, you can exchange the sleeve in no time. You will find instruction videos on changing the sleeve on the website from AKO.
By the way: The valve housing does not have to be replaced here, but rather can be reintegrated into the system with a new sleeve.
On the website from AKO valves, we have provided a number of assembly and/or repair videos that support you in the maintenance of your abrasion-resistant valves. To the AKO video portal.
Do you use aggressive or abrasive media? Are you looking for an economical and effective alternative to your conventional shut-off and control valves? Then send us your requirements for an abrasion-resistant valve and our consultants will figure out the right valve configuration for you. You can also contact us by telephone.
Since abrasion-resistant valves are configured using a modular system, they are ideally designed for the requirements of the medium and application. You can choose from a wide range of elastomer qualities, housing and connection materials, as well as all common connection types of industrial pipeline system.
As the market leader in the pinch valve segment, AKO also relies on a solution in which compressed air is applied to the valve in the case of its abrasion-resistant valves. The function is the same as for conventional pinch valves. The significant difference, however, is inside the valve: Here, a particularly wear-resistant sleeve is used.
For the sleeves of abrasion-resistant valves, various production methods fundamentally come into consideration. These methods depend on the valve type in which the sleeve will later be used. This includes numerous winding techniques, manual assembly or conventional injection methods. The quality of the compound is much more decisive than the structure of the abrasion-resistant sleeves. In the process, the simple formula applies:
Better compound quality
Longer sleeve life time
Lower maintenance costs and fewer downtimes
Global market leader
Unique delivery promise
Widest pinch valve product range
Extensive service activities
