Electric cut-off valve
Simple introduction
J941H electric globe valve consists of electric actuator and globe valve.The valve body material variety is complete, the packing, the whole piece may according to the actual working condition or the user request reasonable choice matches, can apply to 1000 each kind of pressure, the temperature and the medium working condition.
Valve in the pipeline is mainly used to cut off, distribution and change the flow of the medium side, generally do not do adjustment, because the adjustment of unbalanced force is too large, the erosion of the valve core is more severe damage.Suitable for water supply and drainage, petrochemical, metallurgy and other occasions with high pressure.
Electric valve is thousand forced sealed valve, the valve is closed, must be pressure on the disc, to force a seal face don't leak, when the medium from the disc below to the valve, operating force required to overcome resistance, is stem and packing friction with the thrust produced by medium pressure, close the valve force stronger than open the valve, so it's bigger, the diameter of the stem or stem top bending failure happens.
