ASCO™ Series 045 Pinch Valves
Series 045_Pinch Mechanism
The ASCO Series 045 is a line of 2-way and 3-way normally closed and normally open solenoid-operated pinch valves designed for use with highly aggressive or high-purity liquids in analytical, life science, and medical instrumentation.
Hermetic separation of the control mechanism and the fluid within the tubing prevents particulate contamination caused by friction of the moving parts - assuring maximum purity of liquids. Typical applications include hemodialysis, bioinstrumentation, surgical fluid management, and pharmaceutical equipment.
