This specific 3/4” (DN 20) valve is rated for Class 150 service. It has a flange diameter of 100 mm, a bore of 69.9 mm, a flange thickness of 15.9 mm, and uses four bolts of 1/2” size. The face-to-face length is 203 mm. It is manufactured from materials compatible with oil and gas environments and meets ASME B16.34, API 6D, and ISO 17292 standards for pressure-temperature performance and reliability.

The Double Block and Bleed Valve with Flange x Thread connections and Ball x Ball isolation with Needle Drain is a compact assembly designed to provide dual isolation in oil and gas systems. The two ball valves ensure reliable upstream and downstream shutoff, while the needle drain allows controlled venting, sampling, or pressure release between the isolation points. This design reduces the number of flanged joints and potential leak paths, improving safety and reliability in instrument and process applications.

The valve is available in sizes from ½ inch to 2 inch and pressure classes from 150 to 2500, making it suitable for a wide range of process conditions. It can be manufactured in various materials including SS 316, SS 316L, Duplex, Super Duplex, Hastelloy, Inconel, and Monel, and can be supplied to meet NACE MR-01-75 requirements. The assembly is built to recognized standards including ASME B16.34, API 6D, and ISO 17292 and is tested to ensure proper operation, minimal leakage, and long service life.

This valve is ideal for instrument isolation, gauge protection, chemical injection, sampling connections, and other applications where safe and reliable dual isolation is required. Its compact and integrated design reduces installation complexity, simplifies system layout, and provides a safer and more efficient solution compared to assembling individual valves.

The 2 Valve Manifold T Type – Pipe to Flange 1/2” Female NPT is designed to provide a reliable and compact solution for connecting impulse lines to pressure transmitters and gauges. This manifold allows operators to safely isolate instruments from the process for maintenance, calibration, or testing, without the need to shut down the system. The T-type configuration features two valves that control flow to and from the instrument, enabling efficient block, bleed, and vent operations.

The pipe-to-pipe design ensures a direct connection to the piping system, which reduces potential leak points and simplifies installation. It is suitable for high-pressure applications, with a standard working pressure of 6000 PSI and options available for higher pressures. The manifold is built with a metal-to-metal body and bonnet seal for enhanced durability and temperature resistance, with materials that can comply with NACE MR 01 75 standards for corrosion resistance.

Additional features include a removable T-handle for low-torque operation, self-centering non-rotating stems for consistent shutoff, and a dust cap to prevent contamination. Packing is positioned below the stem threads to isolate the threads from the process media, and the stem’s rolled threads provide smooth operation and long life. The manifold is 100% factory tested for leakage and performance, ensuring reliable operation in critical oil and gas 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.
