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.
Hastelloy high-pressure needle valves are made of high-performance nickel based alloys such as Hastelloy C276 or B3
Adopting a 90 ° right angle flow channel design, it is suitable for pipeline systems with high pressure, high viscosity, or media containing micro particles. The conical needle valve core is matched with a hard alloy sealing surface to achieve precise flow regulation and tight shut-off.
The high-pressure double needle valve with ferrules is made of high-strength stainless steel and integrates two independent needle valve cores.
