Pinch Valves (9 products containing 74 Items)


Hose valves—also known as sleeve valves—are ideal for use with abrasive, fibrous and solid products, such as emulsions, powders, slurry and granules. This is due to the specific properties of their flexible rubber sleeve. In addition, hose valves are ideal for applications and systems in which an accumulation or increase of a product can occur.


Hose valves have a wealth of applications: in the chemical industry, in the construction and cement industry, in environmental technology and in water-purification plants, in vehicles and silos, in the food industry, in air and vacuum transport systems and in the plastics industry.


Hose valves have just four components; the casing, the sleeve or hose and the two connectors. A hose valve does not require a separate actuator to operate, just a 2/3 solenoid valve for control purposes. Due to the low volume of the flat, elliptical casing, only a minimal amount of compressed air is required to seal the sleeve.


The quality of each sleeve is largely responsible for the quality of the hose valve. A sleeve consists of several layers and is produced by various stages of manual and machine production. The fibre reinforcements in the various layers ensure that the sleeve is deformed in the proper way when the valve opens and closes. In addition to the correct choice of material, the synchronisation of the product pressure and pilot pressure also affects the service life of the sleeve.


One of the advantages of hose valves is their space-saving application. Furthermore, these valves allow the product to pass through unrestricted, which ensures free flow and minimum flow resistance. Thanks to their simple and lightweight construction, hose valves are highly efficient and user-friendly. Hose valves are available with an aluminium, stainless steel or plastic casing and a wide range of sleeve materials.
