Note:

Gauge Root Valve Male x Female isolates pressure gauges in oil and gas systems for safe maintenance and calibration.

Executive Summary

Gauge Root Valves with Male x Female connections are used in oil and gas systems to safely isolate pressure gauges for maintenance, calibration, or replacement without interrupting the main process. The Male x Female connection allows easy integration into existing piping or instrument lines while providing a secure, leak-proof fit.

These valves protect gauges from overpressure and system fluctuations, ensure accurate readings, and reduce the risk of downtime or safety hazards. They are rated for pressures up to 6000 PSI, and are tested to ASME B16.34 and MSS-SP-99 standards for reliability and long-term performance.

Detailed Description

The Gauge Root Valve Male x Female is a high-pressure valve designed for precise isolation and control of gauge lines in oil and gas industry. It allows for secure attachment of pressure gauges or instruments while maintaining reliable sealing and flow control. The male x female connection simplifies installation by providing a compact and leak-resistant interface, suitable for both standard and custom piping setups.

This valve is built to withstand pressures up to 6000 psi, with optional higher ratings available upon request, and operates over a wide temperature range from -50°C to 230°C, with extended ratings up to 500°C when using graphite seals. The metal-to-metal body bonnet seal ensures consistent high-pressure performance without relying on O-rings.

The valve’s stem incorporates a backseat design for added safety, rolled threads for smooth operation, and a self-centering, non-rotating tip that provides consistent, leakage-free shutoff. Packing is positioned below the stem threads to prevent media contact, and an adjustable gland retainer enhances stability and long-term performance. A removable T-handle enables low-torque operation, while the stem dust cap prevents contamination and protects the actuating threads.

Manufactured to ISO 9001, PED, ATEX, ASME B16.34, and MSS-SP-99 standards, each valve undergoes rigorous factory testing, including pneumatic leak checks at 1000 psi, to ensure reliability and compliance. Optional vibration, temperature, and helium testing can be performed to meet specific process requirements. Heat code traceability and NACE-compliant material options provide confidence in both performance and quality.

This combination of features makes the Gauge Root Valve Male x Female an ideal choice for safe, accurate, and durable gauge isolation in critical industrial systems.
