Pneumatic Pinch Valves

View All Models

Designed for bioprocessing and industrial applications, these models output very strong linear forces when larger tubing or fluid volumes are being displaced. Ideal for pharmaceutical manufacturing systems, Single-Use Disposable applications, food and beverage manufacturing where GMP standards are employed.

When working with harder or larger diameter tubing that requires stronger pinch forces, then our pneumatic product line delivers. Designed for biopharmaceutical processing, food and beverage, and industrial applications where sterility and wash down procedures are needed, these robust units offer reliability and performance. Each model is designed for disposable tubing and contains an easy snap-in tube slot for quick loading and unloading procedures. Panel or base mountable, units can also be configured with optional state sensors, controllers, or setup in normally-open or normally-closed default states. Optional safety caps on larger models are also available to address finger crushing hazards.

Pneumatic Pinch Valve Requirements:
Note that all our pneumatic pinch valves require filtered, clean compressed air that depending on selected model require between 40-100 input psi with a maximum of 125 psi. In addition, units require a solenoid controller for controlling pressurization and ventilation of the chambers between opening and closing states. Customer may select from either 3-way or 4-way controller options offered by Acro that have been thoroughly tested and validated for use with our models.
