The R Type configuration is particularly suitable when multiple valve functions are needed in a compact layout. By combining all five valves in one manifold, it reduces the number of separate components, minimizes potential leak points, and saves installation space compared to using individual valves.

This manifold is ideal for environments where reliability and safety are critical, offering 6000 PSI standard working pressure, metal-to-metal sealing for high-pressure and temperature performance, and compatibility with NACE MR 01 75 materials. Its design ensures smooth operation, low torque handling, and long-term durability, making it the preferred choice for complex measurement and control systems in oil and gas operations.

The Gauge Root Bleed Valve with vent tube and handle is a high-pressure valve designed to provide safe venting and pressure release in industrial and oil and gas systems. It is typically installed in high-pressure piping where pressure gauges or instruments are connected, allowing operators to isolate and safely bleed off pressure for maintenance, calibration, or inspection. The vent tube directs released media away from the operator, reducing the risk of injury or contamination, while the handle provides easy and precise manual operation.

This valve is rated for 6000 PSI standard working pressure, with higher pressures available on request, and is constructed with a metal-to-metal body and bonnet seal for reliable sealing at high temperatures and pressures. It features a backseat stem for added security, a self-centering, non-rotating tip to ensure leak-free performance, and a simple adjustable gland retainer to maintain packing stability over time.

Factory testing includes pneumatic tests with nitrogen at 1000 PSI to verify seat and packing integrity, with a maximum allowable leak rate of 0.1 sec/min. The valve materials can be supplied in stainless steel or other corrosion-resistant alloys and are compatible with NACE MR 01-75 standards. Heat code traceability ensures quality control and material verification for critical applications.

This valve is essential for safely isolating and venting pressure from instruments, gauges, or process line.

The HDI 2200 Choke Position Indicator System is a battery-powered, intrinsically safe solid-state electronic gauge designed to monitor choke valve positions in oil and gas operations with high accuracy. It displays choke position in 1% increments from fully closed to fully open (0% to 100%) using a three-digit numeric readout alongside an analog bar graph segmented into 101 divisions for both precise measurement and quick visual trend analysis.

The system interfaces with linear, rotary, or retractable potentiometers housed in stainless steel enclosures. This flexibility allows for straightforward adaptation across many choke configurations without the need for onsite customization. The sealed stainless steel housing and solid-state electronics enable the 2200 to operate reliably in harsh field conditions, including high vibration environments typical in land and offshore drilling.

Its compact display unit measures approximately 8 by 8 by 4 inches and weighs around 5 pounds. The system is powered by an intrinsically safe 3.6V DC battery pack, with a low battery indicator to ensure timely maintenance and uninterrupted operation. Field-repairable components minimize downtime and allow for easy servicing. The system supports dual sensors for integration with human-machine interfaces (HMI) or programmable logic controllers (PLC), enabling remote monitoring and automation. The 2200 system replaces traditional pneumatic indicators, eliminating the need for air lines and reducing maintenance complexity, while offering a simple calibration interface to facilitate setup and ongoing adjustments.

Hex Reducing Nipples Male NPT are pipe fittings designed to connect two female-threaded pipes of different diameters while maintaining a secure and leak-resistant seal. The male tapered threads provide a tight connection that prevents fluid leakage, which is especially important in high-pressure systems.

These fittings are widely used in the oil and gas industry, chemical processing, and instrumentation applications where a reduction in pipe size is required without adding extra joints.

They are manufactured from high-quality materials such as stainless steel, brass, and other compatible alloys, ensuring durability and resistance to corrosion. The fittings are precision-machined from bar stock to provide burr-free internal surfaces for smooth flow and to reduce turbulence within the system. Threads are carefully capped and packed to prevent damage during transit.

Hex Reducing Nipples are rated for pressures up to 10,000 PSI and comply with ASME B1.20.1, SAE AS71051, ISO 7-1, and ISO 228 standards. They are designed for reliable performance in ambient temperatures from -28 to 37°C (-20 to 100°F) and support efficient installation with standard wrenches thanks to the hex shape, which allows secure tightening.
