Integral Bonnet Tube OD needle valves feature a one-piece construction where the bonnet is integrated with the valve body, eliminating welded joints and providing enhanced strength and safety. This design ensures durability and reliable performance in high-pressure applications, minimizing the risk of leaks or failures.

The Tube OD connections allow secure attachment to tubing while providing precise flow control, making these valves ideal for instrumentation lines, pressure measurement, and process control systems. The design supports consistent, repeatable shut-off and smooth operation, even under demanding conditions.

These valves are particularly suitable for oil and gas applications where high-pressure resistance, leak-free performance, and ease of maintenance are critical. Additional features such as rolled stem threads and mirror-finished stems reduce wear, lower operating torque, and extend service life, ensuring dependable operation in both standard and critical environments.

The 5 Valve Manifold R Type – Pipe to Pipe is designed for high-pressure oil and gas applications where differential pressure transmitters or gauges need to be connected, calibrated, and maintained safely. This manifold provides two block valves, two equalizer valves, and one bleed valve in a single assembly, allowing operators to isolate the transmitter, equalize pressure between impulse lines, and safely vent pressure when required.

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.
