Seamless Strength. Welded Safety. Zero Leakage.
At Perfect Engineers, we manufacture Socket Weld Needle Valves for industrial flow control systems that demand leak-tight shut-off, high-pressure endurance, and permanent inline connection. Engineered from forged or bar stock bodies, these valves feature socket weld (SW) ends as per ASME B16.11, suitable for 6000 PSI and higher pressure applications.
Ideal for oil & gas pipelines, steam headers, chemical injection systems, and energy sector skids, our socket weld valves are preferred where threaded joints are not acceptable due to vibration, safety, or process conditions.
A Socket Weld Needle Valve is a manual valve with weldable ends, where pipe is inserted into a recessed socket and then fillet-welded. It provides a strong, permanent, leak-proof connection in high-pressure, high-temperature lines where threading may fail or leak over time.
These valves are best suited for critical services, including steam, hydraulic oil, high-temperature gas, and chemical media.

Socket weld valves are welded to the pipe for a permanent, leak-proof connection, while threaded valves can be disassembled but are prone to vibration-related leaks.
Yes. With graphite or metal-to-metal seats, these valves handle high-pressure and high-temperature steam lines efficiently.
Absolutely. All socket weld ends conform to ASME B16.11 and are machined with precision gauges.
Yes. We manufacture exotic alloy socket weld valves for corrosive and offshore services.
Common sizes and materials are usually in ready stock. Custom builds take 7–14 working days.
