Male to Female Thread 1/2″ NPT Lagging Extension Body Gauge Valve

Specification:

 Stainless Steel Male to Female Thread 1/2″ NPT Lagging Extension Body Gauge Valve

Stainless Steel Lagging Extension Body Gauge Valve is a type of instrument isolation valve designed to connect a pressure gauge, pressure switch, or pressure transmitter to a process pipeline. It allows safe isolation, venting, and removal of the gauge for calibration or replacement without interrupting the process line.

Lagging Extension Body Gauge Valve

• Has multiple outlet ports (e.g., side, top, front) in addition to the main process port.

• Allows multiple instruments (e.g., pressure gauge + transmitter) to be connected simultaneously.

• Ports can be used for calibration, venting, or test connections.

• Systems needing pressure indication and transmission at the same point

• Instrumentation manifolds and pressure panels

Typical Features:

• Material: Stainless Steel 316 for corrosion resistance

• Port Size: 1/2″ NPT / BSP

• Working Pressure: up to 6000 PSI

• Type: 2-way, 3-way, or 5-way multi-port designs

• Mounting: Direct or remote

Main Applications:

•Flow Regulation: screwed bonnet needle valves union weld type used in systems where the flow needs to be controlled very precisely, such as in gas or liquid pipelines.

•Testing and Calibration: Frequently used in instrumentation, laboratories, and process control applications to calibrate equipment and regulate test fluids.

•Gas and Liquid Distribution: Hongji Needle valves are common in gas and liquid distribution systems, including those in pharmaceuticals, food and beverage, and oil and gas industries.

•Pressure Control: Often used for controlling the pressure and flow of sensitive or hazardous fluids in applications like fuel systems, high-pressure systems, or critical fluid handling systems.
