The forged butt welded high-pressure needle valve adopts an integral forging structure, with no casting defects in the valve body, high strength, and good impact resistance. It is suitable for high-pressure, high-temperature, or hazardous medium working conditions, and has butt welded connections (BW) at both ends. Fully welded installation with pipelines to ensure zero leakage, widely used in petrochemical, hydrogen energy, LNG, and high-pressure testing systems; The nominal pressure can reach PN100-PN420, and the valve core is designed with a precision conical needle shape, equipped with a hard alloy sealing surface, to achieve precise adjustment of micro flow and reliable and tight shut-off.
Hastelloy high-pressure needle valves are made of high-performance nickel based alloys such as Hastelloy C276 or B3
Used for high temperature, high pressure or extremely dangerous medium systems to eliminate the risk of leakage. The 90 ° angle flow channel design is easy to install and drain, and the precision conical needle valve core is equipped with a hard alloy seal to achieve precise adjustment of micro flow and zero leakage shut-off.
The high-pressure butt-welding double needle valve is integrally forged from high-quality alloy steel or stainless steel, boasting excellent high-pressure resistance.
