Socket Weld Needle Valve Manufacturer in India | Welded End High-Pressure Valves – Perfect Engineers

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.

What is a Socket Weld Needle Valve?

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.
