The high-temperature and high-pressure card sleeve needle valve is made of integral forged heat-resistant alloy steel or stainless steel (such as F316, F321, Inconel 625), suitable for harsh working conditions with working temperatures up to 570 ℃ and pressures up to PN420; The end is connected with double card sleeves, which is easy to install, has good vibration resistance, and maintains reliable sealing under thermal cycling; The internal precision conical needle valve core, combined with a metal hard sealing structure, ensures precise adjustment of micro flow and zero leakage shut-off. It is widely used in high-end industrial fields such as power station instrument pipelines, petrochemical high-temperature reaction systems, supercritical fluids, and hydrogen energy.
Ball head welded needle valve bodies are mostly made of integral forged stainless steel or alloy steel, with a pressure resistance of PN420 or above
Specially designed for high-voltage testing and control systems, with a pressure rating of 20000-60000 psi (138-414MPa).
The forged and welded high-pressure needle valve adopts an integral forging structure, with no casting defects in the valve body, high strength, and good impact resistance
