Designed for use with disposable tube sets, Acro's Model 955 and 958 panel mounted, Solenoid Pinch Valves feature Snap-in Tube Loading with Manual Override for easy replacement of entire fluid path. Valves are virtually maintenance-free and with our internal "Splash Seal" and panel mounting seal, can be cleaned without disassembly. Suitable for vacuum and pressure services, valves can accommodate flexible tubing sizes to 3/8" (9.5 mm) O.D. Options include Analog or Digital Position Feedback, Tube Detection, Noise Suppression, and "Pulse and Hold" control for maximizing valve performance. Critical applications include surgical aspiration and irrigation, blood/plasma handling, dialysis machines, and high viscosity dispensing with the valve frequently being used in conjunction with Peristaltic Pumps to handle the on/off and emergency stop functions. Valves are calibrated specifically for your application and are tested and certified. 25+ years of design experience allows us to customize our standard valves to meet your exact needs.
