PREMA-FLEX Pinch valves


PREMAFLEX pinch valves are pneumatic shut-off devices for liquid, viscous, granular, contaminated, fibrous and aggressive substances. Pinch valves have proven themselves in many different and diverse industry sectors for many years. They are reliable, robust and inexpensive and available in a wide range of nominal sizes. In addition, all valve components are available in a variety of materials to provide you, the customer, with a broad range of applications.


PREMAFLEX pinch valves are primarily used in the pneumatic conveyance of bulk materials of all kinds, in the food and pharmaceutical industry, plastics and chemical industry, environmental technology, wastewater treatment, plant engineering, construction, and mining.


By pressurizing compressed air or liquid via the control port of the PREMAFLEX pinch valve casings, a special, highly elastic rubber sleeve is pressed together. The rubber sleeve closes flush with the central axis and blocks the product flow so that it is completely tight, even with solid inclusions. Due to the highly elastic rubber sleeve, the function is retained even at high switching frequencies. When the control medium is switched off, the rubber sleeve is opened independently by the strong rebound resilience and again releases the defined nominal width cross-section.
