Main characteristics of self operated differential pressure regulating valve

ZZYP, ZZYM type differential pressure regulating valve (micro) is a kind of no external energy saving products, compared with the pressure change and signal process in the pipeline, so that the output force balance force actuator with the medium being transferred, in order to determine the pressure, pressure difference, difference (micro) pressureSelf-actuated regulatorMainly used in various industrial furnace gas combustion system, control a, B two kinds of fuel mixture specific flow, in order to achieve ideal combustion conditions. The self operated differential pressure regulating valve can be used in the sealing oil system of the turbine generator to ensure the normal operation of the generator set and improve the generation efficiency. Self operated differential (micro) pressure control valve can be used for gas, natural gas, liquefied petroleum gas, petroleum gas, nitrogen and other industrial gases decompression, micro pressure regulation. The self operated differential pressure regulating valve produced by Shanghai one ring fluid control equipment Co., Ltd. can also be applied to the differential pressure or micro pressure in the process of petroleum, chemical, metallurgy, pharmaceutical and other industrial sectors, and the automatic adjustment of the balance system.
