ASCO Scientific Series 388, 390, 397 and 401 are 2 Way, normally closed, normally open and magnetic latching solenoid operated pinch valves designed to control the flow of corrosive or high purity fluids in medical equipment and analytical instruments. Pinch valves isolate the fluid from the valve components by locating soft tubing in a mechanism that “pinches” the tubing to block flow and releases to allow flow.

• 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.

• Magnetic latching construction (Series 397) to maintain valve position with loss of power, eliminate coil heat rise, and extend battery life.
