ASCO Isolation Valves are defined by their construction. Sometimes called ‘shielded core valves’ they incorporate a diaphragm that shields the fluid flowing through the valve from the internal components of the solenoid. This is important in applications where the valve is controlling corrosive or high purity fluids. ASCO Scientific’s line includes two broad types of isolation valves - Inert Isolation and General Isolation. ASCO Scientific’s Inert Isolation Valves are constructed with extremely chemically resistant materials such as TFE and PEEK polymers as well as Perfluor elastomers to handle the most aggressive or high purity media. General Isolation Valves are constructed of slightly less chemically resistant materials such as PSU, PEI, FKM, and EPDM for applications that are not as harsh. Our 2 way and 3 way Isolation valves are available in both manifold mount and inline configurations.

Pinch Valves are a unique family of valves that are designed to control fluid by locating soft tubing in a mechanism that squeezes the tubing to block flow and releases it to allow flow. Like Isolation valves, Pinch valves keep the solenoid components isolated from the fluid. The only wetted component is the tubing itself. Pinch valves are designed to be used with Silicone tubing because of its superior resilient qualities. Limited only by the compatibility of Silicone tubing, Pinch valves can be used to control a large variety of fluids. Pinch valves are also useful when controlling fluids with particulate. Our Series S Pinch valves are available in 2 way Normally Open, 2 way Normally Closed, and 3 way versions.
