National standard globe valve is commonly used in globe valve series products. API American standard globe valves execute ANSI and API standards. Valve clack and valve seat welded by Stellite cobalt-based hard alloy with different hardness. It has many advantages, such as reliable sealling, high hardness, wear-resistant, high temperature resistance, anti-corrosion, good abrasion resistance and long service life.
Low temperature globe valves usually refer to working temperature below 110 ℃. They are widely used in liquefied natural gas, liquefied petroleum gas and other industries in low temperature. From 2008, globe valves used below 196 ℃ can be made, all the parts through liquid nitrogen low temperature pretreatment, that completely avoid the seals deformation and leakage in the process.
Forged steel globe valves designed by API 602 standards, and provide three types of valve cover design form: bolt type valve cover; welded type valve cover and pressure autofrettage sealing valve cover, The users can choose different forms according to their needs. At the same time, three types of connection methods, RF Flange, NPT thread and SW welded type can be chosen.
