The Monoflange Single Body Double Block and Bleed Valve combines two isolation points and a vent in a single compact body, providing safe and reliable isolation in oil and gas and process systems. It features a ball isolation mechanism for leak-proof shut-off and a needle drain to safely vent the cavity between the isolation points. This design is particularly suitable for instrument or gauge isolation, chemical injection, sampling, and piping interface applications, where compact size and reduced leak paths are critical.

It's monoflange construction reduces weight, footprint, and the number of potential leak points compared to traditional multi-valve assemblies. The valve accommodates sizes from 1/2” to 2” and pressure classes from 150 to 2500, with both reduced and full bore options to suit different process requirements.

Manufactured from high-quality materials including SS 316, SS 316L, Duplex, Super Duplex, Hastelloy, Inconel, and Monel, the valve can be supplied with NACE-compliant materials for corrosive environments. All units are designed, tested, and certified in accordance with EEMUA 182, API 6D, ISO 17292, and ASME B16.34 standards and are factory tested to ensure reliable dual isolation and controlled cavity venting.

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.

The Monoflange SBB Double Block and Bleed Valve with Flange x Thread connections features an OS&Y isolation valve and a needle drain, providing dual isolation in a single compact assembly. It is designed for oil and gas applications where safe venting of trapped pressure between isolation points is required, such as instrument or gauge isolation, chemical injection, and sampling lines.

The valve’s monoflange design integrates both isolation and venting functions in one unit, reducing the number of joints and potential leak paths while saving space and simplifying installation. The OS&Y isolation valve offers clear visual indication of open or closed status, allowing operators to quickly verify valve position. The needle drain provides controlled venting of pressure trapped between the isolation points, ensuring safe operation during maintenance or sampling procedures.

The valve is suitable for flange sizes from 1/2” to 2” and pressure classes from 150 to 2500, with options for reduced or full bore depending on process requirements. It is available in a variety of materials including stainless steel 316, 316L, duplex, super duplex, Hastelloy, Inconel, and Monel, and can be manufactured to meet NACE MR-0175 standards. The design complies with recognized standards such as ASME B16.34, API 6D, and ISO 17292, and is tested to low emission requirements.

This configuration is ideal for oil and gas operations requiring reliable dual isolation, precise venting, and compact installation in critical piping systems.

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.
