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.
The Y-shaped high-pressure needle valve adopts a Y-shaped flow channel structure, effectively reducing flow resistance and improving flow capacity
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.
