POWERTECH Gauge Root Valve provides an efficient means of mounting gauge and static instrumentation. Our Gauge Root Valves offer a multi-function capability to isolate, calibrate and vent gauge, pressure switches and static instrument applications.
PVI Gauge Valves incorporate high quality needle valves designed to operate at pressures up to 6000 psig with standard PTFE gland packing. The packing is positioned below the stem threads to ensure no contact between system process and the stem threads. The upper gland body is tightened and secured into position by a lock nut. The lower gland body is directly screwed into the component body and secured into place to prevent accidental loosening of the gland body during operation. By offering different outlets, these root valves can suit an assortment of industrial measure positions and handle tasks.

Special/Optional Key Features :
PVI offers Valves with Non-Rotating Tip Stem (NRT) thereby providing tight, repeatable shutoff without the galling or cross-scoring that occurs on V & ball-type stems.
The PVI Gauge Root Valve comes with optional bleed valves to ease of during drainage.
