Detailed Description

The Gauge Root Valve Male x Female with Lagging Extension in 1/4” NPT is a small but robust valve used to safely isolate pressure gauges in pressurized systems. It is designed to handle pressures up to 6000 PSI and temperatures from -50°C to 230°C, providing a reliable seal and leak-free operation. The lagging extension lets the valve be operated without removing insulation, protecting both the system and the operator.

The valve includes features to make it safe and easy to use: a back seat on the stem for extra security, a self-centering non-rotating tip for consistent shutoff, and an adjustable gland retainer to keep the packing tight. The removable T-handle allows smooth operation with minimal effort, while the dust cap prevents dirt or debris from entering the valve. All valves are factory tested for performance, include heat code traceability, and can be made from materials compliant with NACE MR 01-75 for corrosion resistance.

This valve is ideal for oil and gas systems where isolating gauges safely, maintaining insulation, and ensuring reliable operation are essential.
