This design ensures long-lasting, reliable operation while protecting connected instruments and maintaining safety in high-pressure systems.

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 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 1/2" poppet type check valve with male × female NPT connections is designed to allow fluid flow in one direction while preventing backflow in oil and gas systems. Its poppet mechanism provides fast response and a positive seal under pressure, protecting pipelines, pumps, and equipment from reverse flow and pressure fluctuations.

The 1/2" size is suitable for medium diameter lines, instrumentation, sampling, and control applications where reliable uni-directional flow is required. Male × female connections enable secure inline installation and integration into existing piping systems without additional fittings, reducing potential leak points and simplifying system layout.

The valve has a standard working pressure of 6000 psi, with optional configurations up to 10000 psi. Selectable cracking pressures range from 1/3 to 25 psi, allowing precise adaptation to system requirements. Construction materials include corrosion-resistant SS 316, SS 316L, Duplex, Super Duplex, Hastelloy C276, Inconel 625, Monel 400, and Brass, ensuring durability in demanding 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 quality and material verification, and additional testing including vibration, temperature, and helium is available for critical applications requiring high reliability.

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.
