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 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.

HDI Gauge systems used in oil and gas operations are often exposed to harsh environments and continuous use. To maintain accuracy, reduce downtime, and extend the service life of these systems, it is critical to have access to replacement components that are both durable and compatible. A full range of spare parts is available to support maintenance needs, including displays, sensors, cables, processor boards, connectors, and housing elements.

These parts are designed to be interchangeable across compatible models, allowing operators to replace worn or damaged components without requiring full system replacement. This modularity improves cost efficiency and simplifies logistics, especially in remote field locations. Most components are field-replaceable, reducing the need for specialized service technicians and enabling faster return to operation.

Processor boards and display units typically share a common design across multiple gauge models, streamlining inventory requirements and providing flexibility during urgent repairs. Sensors are matched with gauge heads for calibration accuracy but can be easily re-paired and recalibrated in the field or through service support if needed.

Using certified or manufacturer-specified replacement components ensures continued compliance with safety standards, maintains the expected measurement accuracy, and supports the longevity of the equipment. These parts are often backed by service documentation or part tracking for maintenance records and equipment history management.

In short, a well-organized supply of compatible, high-quality parts is essential for effective pressure and temperature gauge system upkeep in demanding industrial settings.

The Gauge Root Valve Female x Female 1/4” NPT is a small but essential valve used to protect and control pressure instruments, like gauges and transmitters, in fluid or gas systems. Its female x female connection allows it to connect directly to two male-threaded fittings, making installation simple and reducing the risk of leaks.

This valve can handle pressures up to 6000 PSI and operates safely across a wide temperature range. The internal stem is designed with a back seat and the packing is placed below the threads, keeping the threads protected from the process media. A self-centering, non-rotating tip ensures a tight seal every time, preventing leaks.

It also features a removable “T” handle for easy turning with low effort, smooth rolled threads for long-lasting use, and a dust cap to prevent dirt or debris from entering the valve. Each valve is factory tested with nitrogen at 1000 PSI to ensure it seals correctly and operates reliably. This type of valve is ideal for isolating and protecting pressure instruments in chemical, oil and gas, and industrial processes.

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.

Hex Reducing Couplings Female NPT are precision pipe fittings designed to connect two pipes of different sizes while maintaining a secure, leak-tight connection. The female NPT threads provide a tapered seal that ensures a tight fit when connected to a male NPT thread, making them suitable for high-pressure systems up to 10,000 PSI. The hex shape of the coupling allows for easy tightening with standard tools, providing both convenience and reliability during installation.

Reducing couplings are specifically used when there is a need to transition between different pipe sizes in a system, allowing for flexibility in design and modification of existing pipelines. They help maintain proper flow rates, pressure, and system integrity without the need for custom fittings. This makes them essential in oil and gas systems where varying pipe sizes are common.

These couplings are manufactured from high-quality materials and are compliant with recognized standards, including ASME B1.20.1, SAE AS71051, ISO 7-1, and ISO 228, ensuring consistency, traceability, and durability in demanding applications. Hex Reducing Couplings Female NPT are ideal for situations where space is limited and a reliable connection between different pipe sizes is required, supporting both operational safety and system efficiency.
