Pinch valves are known for their pinching mechanism of their internal flexible hose, which is typically made of a soft material, like rubber, silicone, and several types of elastomers, to open and close the valve flow path. The best thing about a flexible hose with valves is that it is the only wetted part, and ensures cleanliness of the flow path. Not only that, the flexible hose with valves can easily be maintained and contamination of the other components can be avoided through replacing the hose after it has expended its service life. Due to this, pinch valves can be easily used in applications involving slurries that comprise of fluid containing small solid particles.
Flexible hose with valves: Features and applications
Pinch valves are mostly available as normally open or normally closed. For certain applications requiring high cleanliness, these compact valves are equipped with medical grade silicone or rubber tubing. In some cases, they are used for their squeezing mechanism for other types of tubing that are specified by clients according to the application. For this reason, the flexible hose with valves is capable of dealing with a diverse range of viscous, aggressive, mixture, and purity flow media.
Some of the highlighting features of the flexible hose with valves are:
· High cycle life
· Compact, simple design
· Hose is easily replaceable
· No maintenance is required
· Unobstructed flow path
· Hygienic and easy to clean
Industrial areas for flexible hose with valves
Pinch valves are most preferred for applications where the media and flow path needs to be completely isolated from the rest of the system and avoid entrapments. Common industries where these valves are used include waste water, chemical, ceramic, bulk and solids handling, glass, plastic, drug dispensing, pharmaceuticals, paper mills, and several others. They are also used in clinical analyzers, medical instruments, and a variety of laboratory equipments.
