GAUGE / ROOT VALVE (MALE X FEMALE)
GAUGE / ROOT VALVE (MALE X FEMALE)
A Gauge / Root Valve (Male x Female) is a robust, precision-engineered valve designed for isolating instrumentation devices such as pressure gauges, transmitters, and switches from the process media. With a male inlet and female outlet, this valve enables direct mounting to process lines while facilitating easy removal or servicing of connected instruments.
This valve is essential for process control systems in industries such as oil & gas, petrochemicals, chemical processing, power generation, water treatment, and pharmaceuticals.
- Connection type: Male-threaded inlet x Female-threaded outlet (typically NPT or BSP).
- High-integrity shut-off: Precision needle mechanism for accurate isolation.
- Pressure rating: Up to 6,000 psi (414 bar); higher ratings available on request.
- Compact design: Saves space and simplifies installation close to instruments.
- Blow-out proof stem: Enhances safety in high-pressure applications.
- Stem tip options: Non-rotating, soft-seat, or metal-to-metal for various applications.
- Material options: SS316, SS304, Monel, Hastelloy, carbon steel, and more.
- Packing materials: PTFE or graphite, depending on media and temperature.
- Optional drain / vent port: Allows safe pressure release before gauge removal.
- Protects pressure instruments from direct process pressure surges and enables safe isolation.
- Simplifies maintenance by allowing easy removal of gauges/transmitters without depressurizing the system.
- Versatile mounting with male and female ends suitable for both pipeline and instrument connections.
- Leak-tight design ensures reliable operation in high-pressure systems.
- Improves safety by providing a secure shut-off point close to the instrument.
- Minimizes downtime during instrumentation service or replacement.
