The forged steel extended stem T port low temperature three way ball valve is a professional cryogenic fluid control valve, available in T-port and L-port two flow channel styles. Equipped with customized extended stem, it can isolate low-temperature medium and external operating parts, avoiding stem icing and jamming in ultra-low temperature working environment.
Made of high-strength forged steel and stainless steel raw materials, the valve features integral forging molding, higher structural strength than cast valves. It can realize one-inlet two-outlet fluid diversion, merging and direction switching by 90° spherical rotation.
With standard zero leakage performance conforming to ANSI B16.104, it is widely applied in cryogenic storage tanks, gasification pipelines, petrochemical plants, oil and gas transmission pipelines for long-term stable medium switching operation.
● Compact Low-resistance Structure: Optimized spherical flow channel design, small fluid flow resistance, reduce pipeline medium flow energy loss, energy-saving and efficient operation.
● Fast 90° Switch Operation: Simple spherical core structure, only 90° rotating operation to complete fluid cut-off, diversion and merging, easy operation and high working efficiency.
● Dual Sealing Optional: Support stainless steel movable hard seal and PTFE soft seal, adapt high temperature and low temperature different working conditions separately.
● Anti-icing Extended Stem: Custom lengthened stem design, prevent external water vapor freezing, guarantee flexible valve operation under -40℃ low temperature.
● Diversified Connection Methods: Match RF flange, BW butt welding, RTJ flange three connection standards, meet various on-site pipeline installation demands.
