The Transportation, Shutting Off & Dosing of Chemicals

High performance plants processing chemical substances are often under a lot of pressure to meet environmental legistration and performance demands. Many chemicals are not easy materials to handle, so the correct equipment is required for a smooth, reliable operation on every engineering site.

Whether chemicals are being processed for the protection and preservation of foods, to improve the operation and function of machines, to add colour to materials, make things more durable and resistant, or anything else, they all need transporting, shutting off and dosing along the vast array of pipework within chemical plants. To achieve this, valves to the correct specification carry out this important task, making them a very important part of the chemical industry.


Pinch Valves to suit Chemical Applications

AKO Pinch Valves are successful components in many different chemical plant processes and challenges. Different grades of elastomer sleeves and temperature ratings for inside the pinch valve are offered, to suit the needs of all chemical applications. Largely, EPDM is a common rubber sleeve material, but Natural Rubber, Viton and others are also used for handling chemicals in different forms. Powders, pigments, greases, liquids, slurries, minerals, fibres, emulsions, granulates and dusts are just some of the media types controlled with pinch valves in the chemical industry.

Pinch Valves by AKO handle some of the toughest chemical applications, with their abrasion resistant sleeves performing cycle after cycle. Hygienic pinch valve options are available, with different aseptic and sterile stainless steel configurations to suit every process. Potentially explosive enviornments are also covered with the AKO Pinch Valve, which is available EX Conformed, with a conductive rubber sleeve.
