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.

Close Nipples Male NPT are precision pipe fittings designed to connect two female NPT threaded pipes in oil and gas and process systems. Their short, compact design allows installation in tight spaces while providing a reliable and leak-tight connection. Manufactured from high-quality materials such as stainless steel, brass, or carbon steel, they offer corrosion resistance and durability for demanding industrial environments.

The fittings are produced with burr-free internal surfaces to ensure smooth flow and minimize pressure drop. All threads are tapered in accordance with ASME B1.20.1 and SAE AS71051 standards, allowing secure engagement and leak-free sealing when used with appropriate thread sealants. Close Nipples are suitable for instrumentation lines, pipelines, and other fluid or gas transfer systems where precise alignment and compact installation are required.

They are rated for pressures up to 10,000 PSI, depending on material and size, and are marked with manufacturer, size, material, and heat code for traceability. The fittings are thoroughly cleaned to remove oils, grease, and loose particles, ensuring safe use in sensitive applications. Their simplicity, high-pressure capability, and space-saving design make them a reliable choice for critical connections in oil and gas operations.

The Monoflange DBB Double Block and Bleed Valve with Needle-Needle-Needle configuration is designed to provide dual isolation and safe venting in oil and gas, chemical, and process systems. Both isolation points use needle valves, allowing precise control of flow and pressure in the cavity between the two isolation points, which minimizes leakage and ensures accurate venting. This configuration is particularly suited for instrument and gauge isolation, chemical injection, and sampling applications, where fine control and safety are critical.

The monoflange design integrates the two isolation valves and the bleed into a single compact body. This eliminates the need to bolt together separate valves, reducing the number of joints, potential leak paths, and overall weight, while saving installation space and simplifying maintenance. The valve can accommodate flange sizes from 1/2” to 2” and is rated for Class 150 to Class 2500, making it suitable for a wide range of high-pressure applications.

Manufactured to recognized industry standards including ASME B16.34, API 6D, and ISO 17292, the valve is available in a variety of materials such as SS 316, SS 316L, Duplex, Super Duplex, Hastelloy, Inconel, and Monel. Optional NACE MR-0-175 compliant materials are available for corrosive environments. In-built vent valves and low emission testing ensure the valve meets stringent safety and environmental requirements, providing a reliable solution for critical fluid control applications.

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.

The Gauge Root Valve Male x Female 1/4” NPT is designed to provide reliable isolation and control for pressure measurement instruments in chemical, petrochemical, and oil and gas applications. It allows a secure connection between the process line and pressure gauges, ensuring accurate readings while preventing backflow and leakage. This size is commonly used where compact instrumentation connections are needed, offering precise control in tight piping configurations.

The valve is constructed and tested according to ASME B16.34 for pressure and temperature ratings and complies with ISO 9001, PED, and ATEX standards, confirming quality and suitability for use in hazardous or pressurized environments. It has a standard working pressure of 6000 PSI, with higher pressures available upon request. The metal-to-metal body and bonnet seal ensures high-pressure and temperature performance, and the self-centering, non-rotating stem tip provides consistent shutoff for leak-free operation.
