The HDI 2200 Choke Position Indicator System is a battery-powered, intrinsically safe solid-state electronic gauge designed to monitor choke valve positions in oil and gas operations with high accuracy. It displays choke position in 1% increments from fully closed to fully open (0% to 100%) using a three-digit numeric readout alongside an analog bar graph segmented into 101 divisions for both precise measurement and quick visual trend analysis.

The system interfaces with linear, rotary, or retractable potentiometers housed in stainless steel enclosures. This flexibility allows for straightforward adaptation across many choke configurations without the need for onsite customization. The sealed stainless steel housing and solid-state electronics enable the 2200 to operate reliably in harsh field conditions, including high vibration environments typical in land and offshore drilling.

Its compact display unit measures approximately 8 by 8 by 4 inches and weighs around 5 pounds. The system is powered by an intrinsically safe 3.6V DC battery pack, with a low battery indicator to ensure timely maintenance and uninterrupted operation. Field-repairable components minimize downtime and allow for easy servicing. The system supports dual sensors for integration with human-machine interfaces (HMI) or programmable logic controllers (PLC), enabling remote monitoring and automation. The 2200 system replaces traditional pneumatic indicators, eliminating the need for air lines and reducing maintenance complexity, while offering a simple calibration interface to facilitate setup and ongoing adjustments.

Integral Bonnet Tube OD needle valves feature a one-piece construction where the bonnet is integrated with the valve body, eliminating welded joints and providing enhanced strength and safety.

The Tube OD connections allow secure attachment to tubing while providing precise flow control, making these valves ideal for instrumentation lines, pressure measurement, and process control systems. The design supports consistent, repeatable shut-off and smooth operation, even under demanding conditions.

These valves are particularly suitable for oil and gas applications where high-pressure resistance, leak-free performance, and ease of maintenance are critical. Additional features such as rolled stem threads and mirror-finished stems reduce wear, lower operating torque, and extend service life, ensuring dependable operation in both standard and critical environments.

The 5 Valve Manifold R Type – Pipe to Pipe is designed for high-pressure oil and gas applications where differential pressure transmitters or gauges need to be connected, calibrated, and maintained safely. This manifold provides two block valves, two equalizer valves, and one bleed valve in a single assembly, allowing operators to isolate the transmitter, equalize pressure between impulse lines, and safely vent pressure when required.

The R Type configuration is particularly suitable when multiple valve functions are needed in a compact layout. By combining all five valves in one manifold, it reduces the number of separate components, minimizes potential leak points, and saves installation space compared to using individual valves.

This manifold is ideal for environments where reliability and safety are critical, offering 6000 PSI standard working pressure, metal-to-metal sealing for high-pressure and temperature performance, and compatibility with NACE MR 01 75 materials. Its design ensures smooth operation, low torque handling, and long-term durability, making it the preferred choice for complex measurement and control systems in oil and gas operations.

The Double Block & Bleed Valve – Flange x Flange – Ball x Ball with Needle Drain is a high-performance isolation and venting solution designed specifically for oil and gas applications. This valve combines two independent ball isolation valves and a centrally located needle drain valve within a single, compact body, ensuring reliable double isolation and safe pressure relief or venting.

Manufactured in compliance with ASME B16.34, API 6D, and ISO 17292 standards, it offers assurance of global quality and safety benchmarks. The design accommodates line sizes ranging from ½” to 2”, with pressure ratings from Class 150 up to Class 2500, making it suitable for both standard and high-pressure operations.

The flange x flange connections provide secure installation and easy integration into piping systems, while the ball x ball configuration guarantees tight shut-off. The needle drain allows for controlled venting, sampling, or pressure equalization, enhancing operational safety and efficiency.

The valve is well-suited for critical applications such as pipeline isolation, meter calibration, instrumentation, and maintenance operations in oil and gas facilities. Its compact, space-saving design reduces potential leak paths compared to conventional multi-valve assemblies, lowering installation costs and improving reliability.

Gauge adapters with a female ISO parallel thread to male NPT are small but essential components used to connect measurement instruments, such as pressure gauges or transmitters, to piping systems in industrial and oil and gas applications.

The female ISO thread screws directly onto the instrument, while the male NPT thread connects securely to the pipe or tube, creating a tight and leak-resistant connection.

These adapters are made from high-quality materials such as stainless steel or brass, which makes them durable and resistant to corrosion, even in harsh environments. They are designed to handle high pressures, up to 10,000 PSI, ensuring that instruments provide accurate readings without risk of failure.

They follow international thread standards including ASME B1.20.1, SAE AS71051, ISO 7-1, and ISO 228, which guarantees compatibility with other equipment and ensures reliable performance in critical systems. This makes them a practical and dependable choice for monitoring and controlling fluids.

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. The gauge features a liquid crystal display (LCD) with both a numeric readout and an analog bar graph for quick visual interpretation of choke position. It includes a low battery indicator to ensure continuous operation.

The system is battery powered with a field-replaceable 3.6 Vdc power pack rated for one year of continuous operation. The internal battery powers the gauge electronics but not optional 4-20mA output loops. The 2522 supports up to two additional slave gauges for remote position displays, allowing flexible monitoring setups across control rooms.

Its robust, impact-modified polycarbonate/PBT alloy case is UV stabilized and sealed with gaskets to protect the electronics. The device operates within a temperature range of -40°F to 176°F (-40°C to 80°C) and is suitable for harsh oilfield environments.

Installation is straightforward, with recommended cable lengths up to 1,500 feet between the gauge and potentiometer, and customizable cable options available to fit specific site needs. Each system is factory matched and serialized, supplied with a signed calibration certificate, ensuring accuracy to within ±1% full scale.

Overall, the 2522 system provides a reliable, accurate, and low-maintenance solution for real-time choke position monitoring, enhancing operational control and safety in oil and gas production.

The HDI 1000P Pressure Gauge System is a battery-powered, intrinsically safe electronic gauge used to monitor high-pressure systems in oil and gas operations. It measures pressure using a strain gauge sensor and provides real-time readings on a digital display with both numeric and bar graph formats.
