The HDI V9000 Virtual Choke Console System is a PLC-based control and monitoring platform that provides a digital representation of the traditional hydraulic choke console used in oil and gas operations. It integrates Human-Machine Interface (HMI) technology with electronic joysticks, enabling operators to monitor and control choke valves both locally and remotely.

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 HDI 2000B Pressure Gauge System is a panel-mounted electronic device designed to measure and display high-pressure levels accurately in industrial and oilfield settings. It monitors pressures up to 20,000 psi with an accuracy of plus or minus 0.50 percent of full scale, making it suitable for critical applications where precise pressure monitoring is essential for safety and operational control.

The system consists of two main components: a digital gauge display and a remote pressure sensor connected by an interconnect cable. This design allows the sensor to be installed directly at the pressure source, such as a wellhead, pump, or manifold, while the display is mounted in a more accessible location for easy reading and monitoring.

The gauge features a six-inch liquid crystal display that combines a five-digit numeric readout with an analog bar graph composed of 101 segments. This clear and detailed display makes it easy to quickly understand both the exact pressure value and its trend, even in low-light or harsh environments. The display can be read from up to 35 feet away.

Power is supplied by a replaceable 3.6-volt battery designed to last between 12 and 18 months under continuous operation. Calibration and configuration data are stored in memory that does not require power, ensuring settings remain intact even when the battery is replaced or the system is powered off.

The pressure sensor employs strain gauge technology and is compatible with a wide range of connection types including standard pipe threads and flanges. This allows the system to be used across various equipment and pressure ranges, while simplifying maintenance by enabling cross-compatibility of sensors.

Optional analog outputs provide 4–20 mA or 0–1 volt signals to connect the gauge to control systems, data loggers, or remote displays. This supports centralized monitoring and integration with automated process control.

In oil and gas operations, the 2000B system is commonly used to monitor pressure at wellheads to ensure safe extraction pressures, on pumps to maintain correct fluid flow and prevent overpressure damage, and on manifolds to track pressure differentials between flow lines. Accurate, real-time pressure data from this system helps operators detect anomalies early, avoid equipment failure, and optimize production rates while maintaining safe operating conditions. Its robust design and modular installation make it well-suited for harsh field environments where reliability and ease of maintenance are critical.

Hex Reducing Nipples Male NPT are pipe fittings designed to connect two female-threaded pipes of different diameters while maintaining a secure and leak-resistant seal. The male tapered threads provide a tight connection that prevents fluid leakage, which is especially important in high-pressure systems.

These fittings are widely used in the oil and gas industry, chemical processing, and instrumentation applications where a reduction in pipe size is required without adding extra joints.

They are manufactured from high-quality materials such as stainless steel, brass, and other compatible alloys, ensuring durability and resistance to corrosion. The fittings are precision-machined from bar stock to provide burr-free internal surfaces for smooth flow and to reduce turbulence within the system. Threads are carefully capped and packed to prevent damage during transit.

Hex Reducing Nipples are rated for pressures up to 10,000 PSI and comply with ASME B1.20.1, SAE AS71051, ISO 7-1, and ISO 228 standards. They are designed for reliable performance in ambient temperatures from -28 to 37°C (-20 to 100°F) and support efficient installation with standard wrenches thanks to the hex shape, which allows secure tightening. These features make them suitable for high-pressure and instrumentation piping systems where both reliability and traceability are required.

The 1/2" poppet check valve with female × female NPT connections is designed to allow fluid to flow in only one direction while preventing any backflow. This is important in oil and gas systems because backflow can damage pumps, pipelines, and other equipment. The valve is commonly used in medium-sized lines, instrumentation, sampling, and control applications where reliable flow control is required.

The valve operates at a standard pressure of 6000 psi, with optional configurations available for pressures up to 10000 psi. Cracking pressures, the minimum pressure needed to open the valve, can be selected from 1/3 to 25 psi, giving flexibility to match the needs of specific systems. Its poppet mechanism responds quickly to flow changes and provides a tight seal, ensuring consistent performance and preventing leaks.

Made from corrosion-resistant materials such as SS 316, SS 316L, Duplex, Super Duplex, Hastelloy C276, Inconel 625, Monel 400, and Brass, the valve is suitable for harsh oil and gas environments. Female × female NPT connections allow for secure inline installation without extra fittings, reducing the risk of leaks and simplifying integration into existing piping.

Each valve is factory tested for cracking and reseal performance, ensuring it opens and closes reliably. Heat code traceability is provided to verify material quality. Additional testing, such as vibration, temperature, and helium testing, can be requested for applications requiring high reliability.

This valve is compact, durable, and designed for long-term operation with minimal maintenance. It helps maintain system pressure, protects critical equipment, and ensures that oil and gas systems operate safely and efficiently.

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.
