Dwyer Instruments: Model TNV, PTFE Needle Valve
All PTFE and PCTFE Wetted Parts
The Model TNV PTFE Needle Valve is designed for laboratory and industrial applications for regulating corrosive gases and liquids for high purity services. Media only come in contact with PTFE and PCTFE. Valve spindles are made of ridged PCTFE to minimize "creeping" normally associated with PTFE. The TNV is designed to be used in pressure or non-critical vacuum applications and can be used as a shut off valve.
