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.

The 1522 Choke Position Indicator System delivers accurate, real-time choke valve position information in a robust, easy-to-install package. Its reliable performance, flexible integration capabilities, and low maintenance design support improved flow control, safer operations, and optimized production.

The Check Valve Poppet Type with 3/8" NPT tube ends is a compact valve designed to allow flow in one direction while preventing reverse flow in hydraulic, pneumatic, and industrial systems. It features a spring-loaded poppet mechanism that opens when forward pressure exceeds the cracking pressure and closes immediately when flow attempts to reverse, ensuring reliable protection for pumps, compressors, and other critical equipment.

Rated for a standard working pressure of 6,000 psi, with optional higher-pressure ratings up to 10,000 psi, this valve is suitable for demanding applications in oil and gas, chemical processing, instrumentation, and general industrial environments. The 3/8" NPT tube ends provide secure, leak-tight connections and easy integration into medium-diameter piping or tubing systems.

The poppet design minimizes pressure drop while delivering fast response and tight sealing, reducing the risk of backflow and system inefficiency. Built from durable materials such as stainless steel, Duplex, Super Duplex, Hastelloy, Inconel, or Monel, the valve offers long service life even in corrosive or high-pressure conditions. Factory testing ensures each valve meets standards for cracking and reseal performance, with heat code traceability for full material verification.

This type of valve is particularly effective in applications requiring precise flow control, compact installation, and reliable one-way operation, making it an essential component for maintaining system integrity and protecting valuable equipment.

The Tube Fittings Male Connector with ISO Parallel Thread is designed to join tubing to parallel-threaded ports in high-pressure systems. This fitting ensures a tight, leak-resistant seal that maintains system integrity under pressures up to 6000 PSI, making it suitable for demanding oil and gas applications.

Constructed from high-quality materials, the fitting is manufactured to precise tolerances to ensure proper ferrule deformation and consistent performance. The parallel thread design allows for a straightforward installation and secure connection without excessive torque, reducing the risk of thread damage or galling.

These fittings are used extensively in pipelines, instrumentation, and process systems where a reliable and durable connection is required. The male connector configuration allows it to mate with female threaded components, providing versatility in system design. The robust design also ensures excellent performance under vibration, temperature changes, and fluctuating pressures.

Overall, this fitting combines technical reliability with ease of use, making it suitable for both engineering and operational personnel who require dependable tubing connections in oil and gas environments.

The Mini Needle Valve Series – Male x Female is designed for accurate and reliable flow control in small or compact piping systems. Its male-to-female connections allow easy integration into existing instrumentation or process lines. The valve ensures bubble-tight shut-off, preventing leaks in sensitive applications.

The rolled stem threads provide smooth operation, strength, and long service life, while the mirror-finished stem reduces friction, extends packing life, and ensures consistent performance. Packing located below the stem threads prevents lubricant washout, protects against corrosion, and keeps solids from entering the thread area, which could cause damage.

With low operating torque, these valves are easy to operate even in tight spaces. Optional panel-mount versions allow installation in control panels or instrument assemblies, making them ideal for oil and gas, chemical, and other industrial applications where precise flow control is essential.

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 2000P Pressure Gauge System is a solid-state electronic gauge designed to provide accurate and reliable pressure measurement in demanding industrial and oilfield environments. It is suitable for monitoring pressures up to 20,000 psi and is built to operate safely in hazardous locations.

The system includes a gauge display, inline cable, and a matched pressure sensor. The gauge features a 6-inch diameter LCD with a numeric display and a 101-segment analog bar graph for trend indication.
