The 1/2" poppet check valve with female × female NPT connections is designed to allow fluid to flow in only one direction while preventing any backflow. This is important in oil and gas systems because backflow can damage pumps, pipelines, and other equipment. The valve is commonly used in medium-sized lines, instrumentation, sampling, and control applications where reliable flow control is required.

The valve operates at a standard pressure of 6000 psi, with optional configurations available for pressures up to 10000 psi. Cracking pressures, the minimum pressure needed to open the valve, can be selected from 1/3 to 25 psi, giving flexibility to match the needs of specific systems. Its poppet mechanism responds quickly to flow changes and provides a tight seal, ensuring consistent performance and preventing leaks.

Made from corrosion-resistant materials such as SS 316, SS 316L, Duplex, Super Duplex, Hastelloy C276, Inconel 625, Monel 400, and Brass, the valve is suitable for harsh oil and gas environments. Female × female NPT connections allow for secure inline installation without extra fittings, reducing the risk of leaks and simplifying integration into existing piping.

Each valve is factory tested for cracking and reseal performance, ensuring it opens and closes reliably. Heat code traceability is provided to verify material quality. Additional testing, such as vibration, temperature, and helium testing, can be requested for applications requiring high reliability.

This valve is compact, durable, and designed for long-term operation with minimal maintenance. It helps maintain system pressure, protects critical equipment, and ensures that oil and gas systems operate safely and efficiently.

The Monoflange DBB Double Block & Bleed Valve Flange x Thread with OS&Y and Needle Isolation is designed to provide reliable dual isolation with a controlled bleed in a single assembly. This configuration replaces the need for multiple individual valves, reducing the number of potential leak points and simplifying installation in oil and gas applications. The first isolation is achieved using an OS&Y valve, while the second isolation and the drain function use a needle valve, providing precise control over fluid venting and depressurization.

This valve is suitable for instrument and gauge isolation, chemical injection points, sampling connections, and direct or remote mounting of instruments. It supports high-pressure systems with a range from Class 150 to Class 2500, and accommodates both reduced and full bore options. Constructed from durable materials including SS 316, SS 316L, Duplex, Super Duplex, Hastelloy, Inconel, and Monel, the valve can also be supplied with NACE-compliant materials on request.

Manufactured in accordance with recognized standards such as ASME B16.34, API 6D, and ISO 17292, the Monoflange DBB provides a compact, robust solution for dual isolation with reliable venting. Its integrated design reduces stress on piping systems, minimizes maintenance needs, and ensures consistent performance in critical oil and gas applications.

The Needle Valves Integral Bonnet Series – Male x Female is designed for reliable and precise flow control in industrial applications, particularly in oil and gas. Its integral bonnet construction means the body and bonnet are a single piece, eliminating welds and enhancing overall strength, safety, and durability. This design ensures consistent performance under high-pressure conditions and reduces the risk of leakage or mechanical failure.

The Male x Female configuration allows for straightforward installation into piping systems, with the male end threading securely into a female port. This connection type is widely used in process lines, instrumentation, and control systems where accurate flow adjustment, isolation, or sampling is required.

These valves feature a removable T-handle for easy actuation with low torque, rolled stem threads for smooth operation and long service life, and fully supported packing to minimize maintenance. A self-centering, non-rotating stem tip ensures bubble-tight shutoff, while the mirror-finished stem reduces wear on packing and facilitates smooth operation. Optional stellite-tipped stems are available for applications involving abrasive or corrosive fluids, further extending the valve’s lifespan.

This series is ideal for applications requiring precise flow control, reliable sealing, and long-term durability in harsh environments such as high-pressure oil and gas systems, chemical process lines, and instrumentation panels.

The HDI 1000B Pressure Gauge System is an intrinsically safe, battery-powered, solid-state electronic pressure gauge designed for accurate and reliable pressure measurement in demanding industrial environments. It measures pressures ranging from 30 psi up to 20,000 psi with an accuracy of ±0.50% of full scale. The system features a durable design with no fluids or moving parts, reducing maintenance requirements and improving long-term reliability.

The gauge includes a clear liquid crystal display (LCD) that combines a five-digit numeric readout for precise pressure values with a 101-segment analog bar graph for quick trend visualization. The display is easily readable in various lighting conditions and includes a low battery indicator to ensure continuous operation.

The 1000B system is modular, comprising a gauge display, inline cable, and sensor assembly. This design allows the display to be positioned close to or remotely from the pressure measurement point, providing flexibility in installation. The system supports multiple connection types including 2” Male NPT, 2” 1502, 2” 2002/2202, or flanged connections to fit different piping standards.

Power is supplied by a replaceable internal 3.6 VDC battery pack, which typically lasts up to 18 months during continuous operation. The gauge system is designed to retain calibration and settings during battery changes or power interruptions, enhancing reliability in field use.

For integration with control systems, the 1000B offers optional 4-20 mA or 0-1 V outputs, enabling remote monitoring, data logging, or connection to PLCs and chart recorders. The system is built to withstand high vibration environments, making it suitable for offshore, drilling, and other heavy industrial applications.

Overall, the 1000B Pressure Gauge System provides a precise, low-maintenance, and versatile solution for pressure measurement needs where safety, accuracy, and durability are critical.

Tube Fittings Male Connector NPT are used to connect tubing directly to threaded pipe systems, ensuring a secure and leak-tight joint in fluid and gas applications. The male NPT threads allow compatibility with standard pipe threads.

These fittings are unique due to their twin ferrule design, which provides a strong mechanical grip on the tubing while creating a reliable seal without requiring welding or additional sealants. The precision-machined ferrules deform evenly to prevent leaks, even under vibration, impulse, or high-pressure conditions.

Straight fittings are manufactured from bar stock, and shaped fittings are made from forgings, offering high structural strength. The case-hardened back ferrules and silver-plated female threads reduce wear and prevent galling, while the radius junction in elbows maintains smooth flow.

Installation is simplified: the tubing is inserted fully to the shoulder of the fitting, and the nut is tightened to specific torque, producing a secure connection. Male Connector NPT fittings are ready for immediate use and can be disassembled and retightened if needed.

Their combination of threaded pipe compatibility, twin ferrule sealing, and ease of installation makes them reliable and widely used in demanding industrial applications.
