HDI Gauge systems used in oil and gas operations are often exposed to harsh environments and continuous use. To maintain accuracy, reduce downtime, and extend the service life of these systems, it is critical to have access to replacement components that are both durable and compatible. A full range of spare parts is available to support maintenance needs, including displays, sensors, cables, processor boards, connectors, and housing elements.

These parts are designed to be interchangeable across compatible models, allowing operators to replace worn or damaged components without requiring full system replacement. This modularity improves cost efficiency and simplifies logistics, especially in remote field locations. Most components are field-replaceable, reducing the need for specialized service technicians and enabling faster return to operation.

Processor boards and display units typically share a common design across multiple gauge models, streamlining inventory requirements and providing flexibility during urgent repairs. Sensors are matched with gauge heads for calibration accuracy but can be easily re-paired and recalibrated in the field or through service support if needed.

Using certified or manufacturer-specified replacement components ensures continued compliance with safety standards, maintains the expected measurement accuracy, and supports the longevity of the equipment. These parts are often backed by service documentation or part tracking for maintenance records and equipment history management.

In short, a well-organized supply of compatible, high-quality parts is essential for effective pressure and temperature gauge system upkeep in demanding industrial settings.

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.

The HDI 2522 Choke Position Indicator System is a 4-inch solid-state electronic device used to precisely monitor the position of chokes in oil and gas operations. It provides position readings in 1% increments from fully closed (0%) to fully open (100%). The system supports a variety of choke types by interfacing with linear, rotary, or retractable potentiometers, making it adaptable to different choke designs commonly used in the industry.

This indicator eliminates the need for pneumatic air lines traditionally used for position sensing, improving reliability and reducing maintenance requirements.
