Valves for Chemicals and other Media
Pinch valves are increasingly becoming popular in industries that involve handling corrosive and fibrous materials. This type of valve is highly suitable for such applications because they use a 100% tight blocking method and have the ability to shut easily and quickly. Not only that, valves for chemicals with a pinching sleeve mechanism are known for the high versatility in applications with specific operating temperature requirements.
Pinch valves can be used for a number of materials, ranging from radioactive materials to corrosive fluids and gases, and are designed to withstand wear and tear caused by heavy usage. Such applications may require handling abrasive slurries, highly reactive chemicals, and hot steam. They can also be paired with several accessories for enhancing their functionality such as pressure regulators, solenoid valves, pressure switches, and other accessories suitable for valves for chemicals.
The Working Mechanism of Valves for Chemicals
Being solenoid-operated devices, valves for chemicals with a pinching sleeve used in applications involving different types of chemicals are available in several different configurations, namely, normally open and normally closed. These valves for chemicals are designed to give complete control over flow of the media through its efficient open and shut tubing operation. One of the benefits is that the sleeve is the only part that comes in contact with the media, making it a cost-effective solution as well. The sleeve is held in place with the help of the grooves and the different types of end connections that attach to either end of the body.

For the air operated type of valves for chemicals, air is applied into the side of the valve casing through a nipple. This air then forces the rubber sleeve inside the body to collapse, and pinch tightly together to shut off the product flow, such as chemicals.
Some of the most common application areas of pinch valves are chemical, food and beverage, medical, and bio-processing industries. See more application areas showing photos of AKO Pinch Valves in situ.
