PTFE or PEEK Media Isolation Valves

The NIV Series bidirectional isolation valves are solenoid-operated devices that use a flexible diaphragm to isolate the actuation mechanism from the fluid path. Isolation valves are commonly used for a wide variety of applications, including those that require precise, repeatable dispensing of media.

Electronic Pinch Valves

Pinch valves are an excellent alternative to traditional mechanical valves when media contamination is a concern, as they interact with medical- or food-grade tubing and never touch the material being dispensed. This compact electronic series offers four styles with multiple sizes, tubing, and pressure options.

Pneumatic Pinch Valves

The NPP Series are air-piloted devices designed to open and close tubes for controlling the flow of liquids and gases. While other valves have internal passages that may cause small amounts of fluid to remain in the valve, pinch valves have no areas or dead volume where fluid can become trapped. Only the inside of the tubing has contact with the fluid.

Isolation Valves

Isolation and pinch valves provide media isolation characteristics to handle a variety of applications where system protection and/or media compatibility are important. Each series of valves features low power consumption, a compact design, and a high cycle life.
