Media Isolation Valve
Clippard's NIV series media isolation valves come in four sizes and feature unique one-piece valve stem.
Clippard introduced 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 PTFE, making this series suitable for use with corrosive media. The series incorporates a one-piece valve stem that functions as a sealing membrane while also supporting and centralizing the poppet in the seating area. This multifunctional 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 series offers 4 orifice sizes available as 2-Way Normally-Closed, 2-Way Normally-Open, or 3-Way Selector/Diverter. The valves meet CE and RoHS compliance.
