Forged steel by the valve on the basis of API602 scale planning production, supply three kinds of valve cover planning situation: valve cover screw type, welding type bonnet, pressure from tightly closed valve cover, the user can certificate indispensable choose difference situation, supply the RF flange, NPT turnbuckle, SW welding type three kind of connection method. Warm jacket by the valve to accept warm jacket planning, use external hot objects in external circulation heating valve, can be useful on the media after the valve temperature loss, guarantee the temperature of the medium. Q: the use of various different by the valve to a: forged steel by the valve on the basis of API602 scale planning production, supply three kinds of valve cover planning situation: screw type bonnet, burn and welded bonnet, pressure from tightly closed valve cover, the user can certificate indispensable choose difference situation, supply the RF flange, NPT turnbuckle, SW welding type three kind of connection method. 。 National standard by the national standard by the end of valve is one of the most commonly used by the valve series products, the tightly closed side of the seat and disc accept difference of hardness is too set ( Stellite) Cobalt-based hard alloy surfacing and become, is tightly closed good, high hardness, wear resistance, high temperature resistant, resistant to decay, good abrasion resistance, long duration of survival. API by American standard valve by valve American standard ANSI and API, disc and seat tightly closed surface accept difference of hardness too stand ( Stellite) Cobalt-based hard alloy surfacing and become, is tightly closed good, high hardness, wear resistance, high temperature resistant, resistant to decay, good abrasion resistance, long duration of survival. Fluorine-butterfly practical in - as of valve fluorine-butterfly by valve 50 ~ 150 ℃ of liquid concentration aqua regia, sulfuric acid, hydrochloric acid, hydrofluoric acid, and a variety of organic acids, strong acid, oxygen agent, also suitable for a variety of strong alkali liquid concentration of organic solvents and other corrupt gas, the liquid medium used on the pipeline. Now a practical temperature up to - can be made up 196 ℃ by the end of valve, all parts accept liquid nitrogen at low temperature pretest punishment punishment, absolutely stop the use of process tightly closed variant. Plunger valve plunger valve and piston by the valve, the radial tightly closed tightly closed surface accept layout, by the set of the fortress of two elastic ground beam tightly closed circle after connection of body and bonnet screws to give on the cover of load elastic tightly closed circle around the plunger pressure Marine valve successfully implemented by the valve tightly closed. Low temperature by the end of valve by valve temperature below - generally refers to things at low temperature 110 ℃ Industrial Valves, everywhere is applied in liquefied natural gas (LNG), liquefied foreign oil gas and other industries in low temperature. Needle valve type needle valve is a kind of small diameter gauge valve, whole pipeline in instrument measurement system for the opening and closing and the correct flow rate of the conjugate manufacturing, shut a plant instrument series, oilfield special series, series and so on.
