ASCO Scientific Series 373 and 443 are patented 3 Way solenoid operated pinch valves designed to divert or select the flow of corrosive or high purity fluids in medical equipment and analytical instruments. The fluid is isolated from the valve components by means of silicone tubing and flow is controlled in either direction by the alternating pinching action of the solenoid.

• Saves space in equipment with compact design.

• Low power consumption to reduce power supply requirements.

• Large range of tubing sizes available for various flow and pressure requirements.
