These solenoid-operated 2- and 3-Way pinch valves are ideal for use with fluids that are difficult for traditional solenoid valves to handle, such as viscous fluids. They are ideal for on/off flow control applications and where frequent changes of wetted parts are necessary. All models are compatible with silicone, C-FLEX®, and PharMed® BPT tubing. The two-way valves are available in both normally closed and normally open configurations. The three-way valves accept two tubes, the bottom tube is normally open while the top is normally closed.
