Clippard NIV Series designed for use with corrosive media.

Clippard released its NIV Series Media Isolation Valve , a solenoid-operated device that uses a flexible diaphragm to isolate the actuation mechanism from the fluid path. All wetted areas of the valve are either PEEK or PTFE, making this series ideal for use with corrosive media. The series features a one-piece valve stem that functions as a sealing membrane while also supporting and centralizing the poppet in the seating area. This multi-functional poppet/diaphragm/stem results in a simplified design with fewer parts (only two for the 2-Way and three for the 3-Way), longer life and zero dead volume, the company says. The series comes in four orifice sizes available as 2-Way Normally-Closed, 2-Way Normally-Open, or 3-Way Selector/Diverter.
