This setup is particularly useful in oil and gas, petrochemical, and process control applications where continuous operation is critical.

The manifold is built with 1/2” Female NPT Pipe to Flange connections set on 54mm (2-1/8”) centers, providing standardized and secure interfacing with pressure transmitters. High-quality construction includes metal-to-metal body and bonnet seals to withstand pressures up to 6000 PSI and temperatures ranging from -50°C to 230°C, with higher temperature ratings available using graphite materials. The design ensures leak-free performance through features such as self-centering, non-rotating valve tips, back-seated stems for added security, and rolled threads for smooth operation.

Additional operational benefits include easily adjustable gland retainers for maximum packing stability, removable T-handles for low-torque operation, and dust caps to protect actuating threads. Each valve is 100% factory tested, with traceable heat codes, and meets rigorous standards including ASME B16.34, MSS-SP-99, and ASME B31.3, making the manifold a robust and reliable solution for high-pressure industrial applications.

The Gauge Root Valve Male x Female 1/4” NPT is designed to provide reliable isolation and control for pressure measurement instruments in chemical, petrochemical, and oil and gas applications. It allows a secure connection between the process line and pressure gauges, ensuring accurate readings while preventing backflow and leakage. This size is commonly used where compact instrumentation connections are needed, offering precise control in tight piping configurations.

The valve is constructed and tested according to ASME B16.34 for pressure and temperature ratings and complies with ISO 9001, PED, and ATEX standards, confirming quality and suitability for use in hazardous or pressurized environments. It has a standard working pressure of 6000 PSI, with higher pressures available upon request. The metal-to-metal body and bonnet seal ensures high-pressure and temperature performance, and the self-centering, non-rotating stem tip provides consistent shutoff for leak-free operation.

Additional design features include a simple, adjustable gland retainer for stable packing, a back seat for added security, a removable T-handle for low torque operation, and a dust cap to protect the stem from contamination. All valves are 100% factory tested for seat and packing leakage using nitrogen gas at 1000 PSI, ensuring reliable performance. This valve is ideal for isolating and protecting pressure measurement instruments.

The H Type 3 Valve Manifold – Flange to Flange is designed for connecting impulse lines and differential pressure transmitters in oil and gas and industrial process applications. It consists of two block valves, one equalizer valve, and two ¼” Female NPT vent/test connections, providing accurate isolation, calibration, and maintenance of instrumentation.

The manifold is rated for a standard working pressure of 6000 PSI, with maximum ratings up to 10000 PSI available on request. Temperature ratings range from -50°C to 230°C, with 500°C possible using graphite seals. The body features a metal-to-metal seal for high pressure and temperature applications, eliminating the need for O-ring seals, and materials can be supplied according to NACE MR 01 75 standards.

Each valve is 100% factory tested per international pressure standards, including pneumatic testing with nitrogen at 1000 PSI for seat and packing leakage, with a maximum allowable leak rate of 0.1 sec/min. Stems have back seats, rolled threads, and self-centering non-rotating tips for consistent, leak-free operation. The H Type design allows reliable, safe, and precise operation in high-pressure, high-temperature process environments.

The HDI V9000 Virtual Choke Console System is a PLC-based control and monitoring platform that provides a digital representation of the traditional hydraulic choke console used in oil and gas operations. It integrates Human-Machine Interface (HMI) technology with electronic joysticks, enabling operators to monitor and control choke valves both locally and remotely.

This system supports flexible configurations to meet client requirements, including various console layouts and customizable language options. It is designed to interface not only with standard choke control components but also with additional monitoring equipment such as gate valve position indicators, mud gas separator pressure monitors, and environmental sensors for riser and sub-sea temperatures.

By digitizing choke control, the V9000 enhances operational oversight, allowing for precise valve positioning and real-time status feedback. Its modular architecture permits scalability and adaptation to complex wellsite setups, supporting improved safety and efficiency.
