Describes the use of different globe valves
Forged steel globe valve according to API602 scale plan to create three bonnet plans to provide the situation: Bolted bonnet, bonnet bonnet, the pressure from the valve seal precision, the user can choose the necessary circumstances, the RF flange, NPT Threaded, SW welding three kinds of connection methods. Fluorine cut-off valve lined with fluorine globe valve practical in various concentrations of -50 ~ 150 ℃ aqua regia, sulfuric acid, hydrochloric acid, hydrofluoric acid and a variety of organic acids, strong acids, strong oxidants, but also practical in a variety of concentrations of strong alkali organic solvents and Other corrosive gases, liquid medium pipeline use. API American Standard globe valve American Standard Globe valve ANSI and API standards implemented, the valve disc and valve seat sealing surface to accept the differential hardness of Stellite (Stellite) cobalt-based hardfacing surfacing, sealed, high hardness, resistance Grinding, high temperature, corrosion-resistant, anti-abrasion performance, long life. GB stop valve GB stop valve is the most commonly used stop valve series products, seat and valve seal face to accept the differential hardness of Stellite (Stellite) cobalt-based hardfacing surfacing, reliable sealing, high hardness, Wear-resistant, high temperature, corrosion-resistant, anti-abrasion performance, long life. Needle valve needle valve is a kind of small-caliber instrumentation valve, measuring instrument in the pipeline system from the opening and closing and accurate flow control role, an important instrument station series, oil field series, American standard series. Low-temperature shut-off valve Low-temperature shut-off valve usually refers to the affairs of the valve temperature below -110 ℃, used in liquefied natural gas, liquefied kerosene gas and other low-temperature industries. Now the practical temperature of -196 ℃ can be produced cut-off valve, all parts receive liquid nitrogen preconditioning at low temperature, completely prevent the use of sealing deformation during the leak. Piston valve A plunger valve, also known as a plunger stop valve, whose sealing surface receives a radial seal arrangement, is applied to the bonnet by two elastic sealing rings fitted on the buffing plunger through the abutment bolts of the valve body and bonnet Load the elastic seal ring around the plunger to achieve a sealed shut-off valve. Insulation jacket cut-off valve to accept insulation jacket plan, the use of external heat circulating in the valve outside the heating can be useful to prevent the loss of medium temperature through the valve, the temperature of the medium. Forged steel globe valve according to API602 scale plan to create three bonnet plans to provide the situation: Bolted bonnet, bonnet bonnet, the pressure from the valve seal precision, the user can choose the necessary circumstances, the RF flange, NPT Threaded, SW welding three kinds of connection methods.
