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 HDI 1522 Choke Position Indicator System is an electronic instrument designed to accurately measure and display the position of choke valves used in oil and gas production. Choke valves regulate the flow of oil, gas, or water from wells by adjusting the degree of restriction in the pipeline, which directly affects pressure control and production rates. The 1522 system provides highly precise position readings in one percent increments, ranging from fully closed (0%) to fully open (100%), enabling better management of well performance and enhanced safety.

This system uses solid-state electronics to convert mechanical valve movement into electronic signals via various potentiometer types—including linear, rotary, and retractable options—making it adaptable to a wide variety of choke valve designs and configurations. The position data is presented on a four-inch liquid crystal display that combines a numeric readout with a linear bar graph, allowing clear and immediate visualization of the choke’s exact position. The display is engineered for visibility from distances up to fifteen feet, suitable for typical field environments.

Powered by an internal, field-replaceable battery with approximately one year of continuous operation, the 1522 system minimizes maintenance requirements and eliminates the need for complex wiring. It also offers optional analog output signals, such as 4-20 mA or 0-1 V, enabling seamless integration with plant control systems, programmable logic controllers, data acquisition systems, or remote display units for centralized monitoring and automation.

The enclosure is constructed from UV-stabilized, impact-resistant polycarbonate and PBT alloy materials to ensure durability in harsh outdoor conditions. It is rated to operate reliably within a wide temperature range from -40°F to 176°F (-40°C to 80°C). The internal electronics are protected by a gasket seal to prevent dust and moisture ingress, maintaining performance and longevity.

Installation flexibility is enhanced through support for cable lengths up to 1,500 feet, allowing the gauge to be mounted in the most accessible or secure locations. Multiple sensor housing options and connector orientations simplify field installation and reduce the need for onsite customization, helping to minimize downtime and installation costs.

This system supports flexible configurations to meet client requirements, including various console layouts and customizable language options. It is designed to interface not only with standard choke control components but also with additional monitoring equipment such as gate valve position indicators, mud gas separator pressure monitors, and environmental sensors for riser and sub-sea temperatures.

By digitizing choke control, the V9000 enhances operational oversight, allowing for precise valve positioning and real-time status feedback. Its modular architecture permits scalability and adaptation to complex wellsite setups, supporting improved safety and efficiency. The system\'s data logging and reporting features facilitate compliance tracking and operational analysis, making it a comprehensive solution for modern well control management.

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 1/2" poppet type check valve with male × female NPT connections is designed to allow fluid flow in one direction while preventing backflow in oil and gas systems. Its poppet mechanism provides fast response and a positive seal under pressure, protecting pipelines, pumps, and equipment from reverse flow and pressure fluctuations.

The 1/2" size is suitable for medium diameter lines, instrumentation, sampling, and control applications where reliable uni-directional flow is required.
