Its intrinsically safe design provides dependable operation in hazardous locations without compromising safety. The solid-state electronics and durable construction reduce maintenance and downtime, while versatile mounting options allow placement close to the measurement point for accurate readings. Featuring clear numeric and bar graph displays along with remote output capabilities, the system supports timely decision-making and integrates easily with larger monitoring setups, enhancing process control and operational safety in demanding conditions.

The HDI 2250 Valve Position Indicator System provides a reliable method to monitor the open or closed status of manual and hydraulically operated gate valves on choke manifolds. It offers two modes of position verification: a clear visual indicator mounted directly on the valve, and an electronic signal transmitted remotely to control rooms or monitoring systems. This dual feedback delivers real-time valve position information both locally and from a distance, enhancing operational control and safety.

The system is compatible with a wide range of rising and non-rising stem gate valves from various manufacturers, adding position monitoring without compromising valve integrity or certification. An adapter enables installation on valves that lack built-in position feedback. The sensor is an inductive Namur type housed within a rugged 316 stainless steel case, engineered for hazardous oilfield environments. It operates on a 5 to 25 volts DC power supply, making it suitable for integration with most industrial control systems.

Weighing 15.3 pounds with the junction box mounted, the 2250 is built for durability and long-term performance in demanding onshore and offshore conditions. Once installed, it requires minimal maintenance, reducing operational downtime.

The system connects easily to local displays and remote monitoring platforms, offering a comprehensive view of valve positions across the manifold. It supports both Namur and proximity sensors, providing flexibility to meet different installation requirements.

The 2250 stands out for its ability to retrofit manual valves without modification, its robust construction for harsh environments, and dual visual and electronic position reporting. These features make it a practical, dependable choice for improving safety and operational awareness in oil and gas valve management.

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 L type 2 valve manifold is a compact and reliable solution designed for connecting impulse lines to pressure transmitters or gauges in industrial systems. Its primary purpose is to allow safe and efficient measurement of process pressures while providing the ability to isolate, vent, or calibrate instruments without disrupting the process.

The L type configuration refers to the layout of the two valves, arranged in an L shape, which allows for simple and intuitive operation. This design enables the user to block the process pressure, bleed off trapped pressure, and perform calibration on static pressure transmitters or gauges. The arrangement minimizes installation space while ensuring clear and accessible operation.

Pipe to pipe manifolds are designed to connect directly to process lines using standard piping connections. This allows for straightforward integration with impulse lines and reduces the need for additional fittings. The manifold provides a secure and leak-free connection while maintaining easy access for maintenance, calibration, and testing of instruments. Overall, the L type 2 valve manifold combines compact design, operational simplicity, and high reliability for critical measurement applications.

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.
