Our high-performance Electric Actuated pinch valve is a 2/2-way valve designed to shut off or control the flow of corrosive, abrasive, or granular media. In the open position, the valve has no restrictions and allows a wide range of media to pass through the bore. The flexible internal rubber sleeve in the valve keeps the media isolated from the rest of the valve, preventing contamination or damage to the valve's other components. Designed with advanced technology and robust materials, these valves are cost-effective, reliable, and easy to use.

Liquids: Handles suspended solids, slurries, and viscous fluids.
Powders and Granules: Effective for pellets and particulate materials.
Abrasive & Corrosive: Rubber sleeve construction protects the valve body.
The pinch valve consists of a housing, a sleeve, and end connections. The rubber sleeve is the only component that contacts the media. Automatic pinch valves operate using an electric actuator or solenoid to control a plunger that pinches down the sleeve, stopping the flow entirely.
Unlike ball or gate valves where particles can get trapped and clog the mechanism, the pinch valve's rubber sleeve closes around particles. Once opened, the sleeve's elastic rebounding property ensures a full, unobstructed flow passage, preventing blockage and reducing wear.
