The high-temperature and high-pressure card sleeve needle valve is made of integral forged heat-resistant alloy steel or stainless steel
¡ð Port type: Card sleeve (BW butt welding, SW socket welding, UBM sleeve welding, threaded, etc.)
¡ð Working temperature: -20 ¡æ~520 ¡æ
¡ð Pressure environment: 6000PSI up to 10000psi (689bar) maximum
¡ð Drive mode: One character handle, handwheel
¡ð Nominal diameter: 3mm~28mm (1/8~1 ")
Valve body material: 304, 316SS, 321, Hastelloy, Monel alloy
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 ¡æ 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 low-temperature and high-pressure welding needle valve adopts a fully welded valve body structure to eliminate the risk of external leakage
The integrated welded double needle valve is primarily used in gas dispensing devices, serving as an instrument root valve or process valve.
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
