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 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 45° Elbow NPT Thread Tube Fitting is a specialized connector used to change the direction of flow in piping systems by 45 degrees. Manufactured to precise standards, it provides a strong, leak-resistant connection between tubes with NPT threads, ensuring consistent system performance. The fitting is suitable for use in oil, gas, and industrial process systems, where controlling flow direction and minimizing stress on tubing is critical.

Its design allows compact and efficient piping layouts, reducing the need for multiple fittings while maintaining smooth fluid flow. The fitting is machined to ensure tight tolerances, providing reliable sealing even under vibration, thermal expansion, or pressure fluctuations. Case-hardened threads improve durability, while the material selection ensures compatibility with common industrial fluids and gases.

Unique to this fitting is its ability to create a precise 45° angle connection without compromising the integrity of the tubing system, making it ideal for applications where space is limited or exact routing is required. Installation is straightforward: the tube is inserted into the fitting, and the NPT threads create a secure mechanical seal that resists leakage over extended operational periods.

The Ball Valve Lever Operated – 2-Way Tube OD End Connection is a high-performance isolation valve designed to start, stop, or regulate fluid flow in oil and gas piping systems. Its 2-way configuration provides a simple and reliable method for controlling flow in a single pipeline, allowing full shut-off or bi-directional flow as needed in production lines, injection lines, sampling lines, or small-diameter process tubing.

The valve features tube OD (outer diameter) connections, which allow direct attachment to tubing without the need for additional fittings. This simplifies installation, reduces potential leak points, and is especially useful in compact piping layouts or systems where welded or threaded connections are impractical.

The floating ball design ensures consistent, leak-proof shut-off even under high-pressure conditions. Operation is simple and efficient with a quarter-turn lever, providing fast control with low torque. The internally loaded stem with shoulder prevents blowout, enhancing safety, and replaceable seats and packings extend service life.

The valve is suitable for a wide range of oil and gas applications where reliable isolation and ease of installation are required.

Integral Bonnet Tube OD needle valves feature a one-piece construction where the bonnet is integrated with the valve body, eliminating welded joints and providing enhanced strength and safety. This design ensures durability and reliable performance in high-pressure applications, minimizing the risk of leaks or failures.

The Tube OD connections allow secure attachment to tubing while providing precise flow control, making these valves ideal for instrumentation lines, pressure measurement, and process control systems. The design supports consistent, repeatable shut-off and smooth operation, even under demanding conditions.

These valves are particularly suitable for oil and gas applications where high-pressure resistance, leak-free performance, and ease of maintenance are critical. Additional features such as rolled stem threads and mirror-finished stems reduce wear, lower operating torque, and extend service life, ensuring dependable operation in both standard and critical environments.
