The high-temperature and high-pressure socket welding needle valve is made of integral forged heat-resistant alloy steel or stainless steel, suitable for harsh working conditions with temperatures up to 570 ℃ and pressures up to PN420; The end is connected by socket welding (SW), which facilitates efficient welding and installation of small-diameter pipelines, with reliable sealing and strong resistance to thermal cycling; The precision conical needle valve core and metal hard sealing structure ensure precise adjustment of micro flow and zero leakage shut-off, and are widely used in key occasions such as power plant instrument pipelines, petrochemical high-temperature reaction systems, and high-pressure steam sampling.
The integrated welded double needle valve is primarily used in gas dispensing devices, serving as an instrument root valve or process valve.
High pressure gauge needle valves are specifically designed for front-end isolation and protection of measuring instruments such as pressure gauges and transmitters
Low temperature and high-pressure needle valves are designed specifically for cryogenic conditions, suitable for temperatures as low as -196 ℃ (liquid nitrogen) or even lower, with pressure ratings up to 10000psi (approximately 68.9MPa).
