Need a compact, strong, and leak-proof valve for high-pressure or small-bore piping systems? At Perfect Engineers, we manufacture and supply high-performance Socket Weld Ball Valves, ideal for steam, oil, gas, chemical, and utility lines where threaded connections aren’t suitable and welding is required for durability.
Socket weld valves are preferred in applications that demand secure joints, minimal leakage, and precision pipe alignment, especially in power plants, refineries, chemical plants, and industrial automation systems.
A Socket Weld Ball Valve is a quarter-turn shut-off valve with recessed ends that allow the pipe to be inserted and welded for a strong, semi-permanent connection. These are best suited for:
