Solenoid Pinch Valve Models
Our solenoid pinch valves are designed to work with flexible tubing, where easy replacement of the entire fluid path is required. These valves are suitable for pressure or vacuum applications.
General Specifications
-
Two-way, normally closed, where the tubing is pinched and the flow is stopped when the valve is in a de-energized state.
-
Capable of pinching flexible tubing sized from 0.125" (3.2 mm) to 0.375" (9.5 mm) OD.
-
Accomodates a tube hardness up to 70 Durometer (Shore A). Upon request higher tubing specifications may also be possible dependent upon the customer requirements.

*Normally-closed (N/C) state: tubing is pinched when the valve is in a de-energized state. Solenoid valves are always normally-closed. If your system required a normally-open state, you require a pneumatic valve.
**Currently available in panel mount designs only.
Power Requirements
Power is a comprehensive measure of a solenoid valve's electrical requirements, incorporating both supply voltage and coil resistance.Coil resistance varies with several factors including supply voltage, tubing, and media pressure. We can wind
solenoid coils for any common DC voltages used in standard medical device and bioprocessing applications.
Functionally, the power required also relates to a valve's stroke and pinching force. Any two of these parameters — power, stroke, pinching force — determines the third. Typical levels of power required for actuation range from 10 to
70 W depending on where the other parameters are set.
