Gauge & Gauge Root Needle Valves
FEATURES & BENEFITS
- Designed for connecting system impulse line & transmitter
- Combine the function of a tee, calibration valve, isolation valve, all tubing and fittings in a single valve configuration
- Allows for easy isolation, calibration, block & bleed for gauges, pressure switches, and static pressure instruments without additional penetration of the main piping
- Bonnet lock pins prevent accidental loosening
- Free swiveling ball end stem (metal seat, std.) assures bubble tight valve closure without seat galling
- Special hardened ball seat is ideal for both gas and liquid service
- All stem packing is located below the stem threads preventing galling, corrosion and contamination
- Adjustable packing reduces the possibility of bonnet/body leaks
- Full back-sealed bonnets prevent accidental stem removal and
blowout
