J41h stop pneumatic valve American standard and national standard by the use of the pneumatic valve

jh by the connection of pneumatic valve in the form of American standard flange connection, the structure form is direct flow pneumatic disc non-equilibrium type, pneumatic valve sealing surface material is Cr stainless steel. Jh by American standard pneumatic valve sealing surface friction small, so durable, suitable for low voltage, can also be applied to high pressure, can use medium wind, water, oil, corrosive medium, such as the highest ability ℃ temperature, can be applied to chemical fertilizer, oil, electric power, pharmaceutical, chemical and other industries on the pipeline, or used to connect truncated to adjust line medium.
jh gb as pneumatic valve adjust flow generally don't have to do, because it is only applicable to all closed and open, if custom, also can adjust and throttling. Sealing surface welding Co in cemented carbide, so corrosion, good frictional resistance and abrasion resistance, can be used in corrosive medium, of course, can be used for oil, gas, water and other media.
jh by American standard pneumatic valve and jh gb as the use of the pneumatic valve is no big difference, only some small details need to pay attention to.
