PANAM Gauge Root Valves are used for the safe installation of pressure switches, gauges and differential pressure transmitters. They are suitable for block and bleed assemblies, for testing the pressure source in sampling lines, or as purge valves.
The valves are built in 316 stainless steel for corrosion resistance, with a schedule 160 or heavier pipe inlet for strength and an extended body for insulation clearance. The non-rotating vee or ball tip forms a bearing joint with the stem, eliminating rotation between tip and seat at closure and ensuring long life in repetitive shut-off service. Optional Grafoil packing is available for high temperatures.
Each valve is hydrostatically tested in accordance with MSS-SP-99 at 1.5 times the maximum working pressure, with seat leakage test at 1.1 times, and nitrogen tested at 1,000 psi for seat, seal and shell leakage. Valves comply with NACE MR0175 / ISO 15156 with heat code traceability.
Key features
- 316 SS construction for corrosion resistance
- Non-rotating vee or ball tip for repetitive shut-off service

- Schedule 160 or heavier pipe valve inlet
- Two 1/2" NPT female gauge ports
- Stem threads isolated from system fluids, rolled and hard plated; safety back seating
- Optional Grafoil packing for high temperatures
