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 Square Body Needle Valve Female x Female is engineered for precise flow control in high-pressure fluid systems commonly found in the oil and gas industry. Its design features a robust square-shaped body, which provides stability during installation and operation, reducing the risk of leaks and mechanical stress. The female x female configuration allows the valve to connect two female-threaded pipes or instrumentation components directly, eliminating the need for additional adapters and simplifying system layout.

The valve operates with a fine-threaded stem that provides smooth, accurate regulation of fluid flow, enabling controlled start, stop, and throttling functions. A metal-to-metal body bonnet seal ensures reliable sealing at high pressures and temperatures, while the back-seated stem and self-centering tip deliver consistent, leak-free shutoff.

These valves are suitable for a range of applications, including instrumentation, process monitoring, sampling, and control systems, where precise flow control and reliable operation are critical. The square body design also facilitates easy wrench access and torque application, making installation and maintenance straightforward in complex piping arrangements.

The Check Valve Poppet Type with 1/4" NPT tube ends is a compact, high-performance valve designed to provide reliable one-way flow control in hydraulic and pneumatic systems. Built for demanding applications, this valve is rated up to 6000 PSI working pressure, making it suitable for both high-pressure and industrial environments.

The poppet design ensures a tight seal when backflow occurs, preventing fluid from moving in the reverse direction while allowing free flow in the intended direction. This not only protects sensitive system components but also maintains system efficiency by eliminating leakage.

With a cracking pressure typically available from 1 to 25 psi, the valve can be selected to suit specific operational needs, ensuring smooth opening without unnecessary resistance. The female NPT tube end connection provides a secure, leak-free fit, compatible with a wide range of standard piping and tubing systems. Constructed from durable stainless steel or carbon steel depending on configuration, the valve offers excellent resistance to wear, corrosion, and high-pressure fatigue.

Commonly used in oil and gas, the poppet-type check valve provides consistent performance, low maintenance requirements, and long service life.

Its simple yet effective design ensures operators can trust it in critical applications where preventing reverse flow is essential for safety and operational reliability.

The 3/8" poppet type check valve with male × female NPT connections is designed for uni-directional flow control and backflow prevention in oil and gas systems. The poppet mechanism provides fast response to flow changes and a positive seal under pressure, ensuring protection of pipelines, pumps, and equipment from reverse flow or pressure transients.

The 3/8" size is suitable for small to medium diameter lines, instrumentation, sampling, and control applications. Male × female NPT connections allow secure inline installation, reducing potential leak points and enabling integration into existing piping without additional adapters.

The valve has a standard working pressure of 6000 psi, with optional configurations rated up to 10000 psi. Selectable cracking pressures range from 1/3 to 25 psi, allowing precise adjustment for system requirements. Construction materials include corrosion resistant SS 316, SS 316L, Duplex, Super Duplex, Hastelloy C276, Inconel 625, Monel 400, and Brass, providing durability in harsh oil and gas environments.

All valves are factory tested for cracking and reseal performance, with pneumatic testing at 1000 psig to verify seat integrity. Heat code traceability ensures material verification, and additional testing including vibration, temperature, and helium is available for critical applications requiring high reliability.

The 3 Valve Manifold T Type – Pipe to Flange is specifically engineered to connect impulse lines to differential pressure transmitters, ensuring accurate measurement and reliable operation in industrial systems. Its T-type configuration features two block valves, one equalizer valve, and vent/test ports, allowing operators to isolate the transmitter, equalize pressure, and perform maintenance or calibration safely without disrupting the overall process. This setup is particularly useful in oil and gas, petrochemical, and process control applications where continuous operation is critical.

The manifold is built with 1/2” Female NPT Pipe to Flange connections set on 54mm (2-1/8”) centers, providing standardized and secure interfacing with pressure transmitters. High-quality construction includes metal-to-metal body and bonnet seals to withstand pressures up to 6000 PSI and temperatures ranging from -50°C to 230°C, with higher temperature ratings available using graphite materials. The design ensures leak-free performance through features such as self-centering, non-rotating valve tips, back-seated stems for added security, and rolled threads for smooth operation.

Additional operational benefits include easily adjustable gland retainers for maximum packing stability, removable T-handles for low-torque operation, and dust caps to protect actuating threads. Each valve is 100% factory tested, with traceable heat codes, and meets rigorous standards including ASME B16.34, MSS-SP-99, and ASME B31.3, making the manifold a robust and reliable solution for high-pressure industrial applications.
