Detailed Description

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.
