Globe valves are classified according to their application: Lined fluorine globe valves are suitable for various concentrations of aqua regia, acid, hydrochloric acid, hydrofluoric acid and various organic acids, strong acids and strong oxidants at -50 ~ 150 ℃. They are also suitable for various concentrations Strong alkali organic solvents and other corrosive gases, liquid media used on the pipeline. API American Standard Globe Valve performs ANSI and API standards. Sealing surfaces of valve disc and valve seat are made of Stellite Co-based hardfacing alloy with different hardness, reliable sealing, high hardness, abrasion resistance and high temperature resistance , Corrosion-resistant, anti-abrasion performance, long life. The national standard globe valve is the most commonly used product in the globe valve series. The sealing face of the valve seat and the valve flap is made of Stellite cobalt base hard alloy with different hardness. The seal is reliable, high hardness, High temperature, corrosion resistance, good scratch resistance, long life. Needle valve needle valve is a small diameter meter valve, measuring instrument in the pipeline system from the opening and closing and accurate flow control role, the main instrument series, oil field series, American standard series. Low-temperature globe valve is usually the valve temperature below -110 ℃, widely used in liquefied natural gas, liquefied petroleum gas and other low-temperature industries. At present, it can manufacture a globe valve with a temperature of -196 ° C. All parts are pre-treated with liquid nitrogen at low temperature to completely avoid seal leakage during use. Piston valve plunger valve, also known as plunger stop valve, the sealing surface using radial seal structure, by the sleeve in the polishing plunger on the two flexible ring through the valve body and the valve cover connection bolts on the valve cover The load presses the elastomeric seal around the plunger to seal the shut-off valve. Insulation jacket cut-off valve insulation jacket design, the use of external heat in the valve outside the cycle of heating, can effectively prevent the medium through the valve temperature loss, to ensure the temperature of the medium. The forged steel globe valve is designed and manufactured in accordance with the API 602 standard and provides three types of bonnet design: bolt bonnet, welded bonnet and pressure self-sealing bonnet. Users can choose different forms according to their needs and provide RF flange, NPT thread, SW welding three connections. Oxygen special globe valve made of good quality brass or stainless steel casting, with high mechanical strength, wear resistance, safety and so on. Used in the oxygen pipeline, with the best explosion-proof flame-retardant properties, eliminating the oxygen pipeline of insecurity, is widely used in steel, metallurgy, petrochemical, chemical oxygen projects such as pipe network. In addition to the function of an ordinary valve, it has its own characteristics. In the manufacture of strict prohibition of oil measures, and all parts are strictly before the installation of degreasing. Corrugated pipe globe valve is made of stainless steel bellows design, reciprocating bellows test 10000 times without failure, reliable sealing performance, suitable for flammable, toxic and harmful medium mining, can effectively prevent the valve leakage phenomenon.
