features

ZZYP, ZZYM type self-reliance pressure differential regulator is an energy saving product without external energy, using pipe pressure change to compare with signal, make the media force and the actuator output force balanced, in order to achieve certain pressure, pressure differential value, self-reliance pressure differential regulator is mainly used in various industrial furnace gas combustion system, control, two kinds of fuel mixture ratio flow to achieve ideal burning conditions. Self-reliance type pressure differential regulator can be used for steam turbine generator sealing oil system, to ensure the normal operation safety and generating electricity to improve efficiency. Self-reliance type pressure differential regulator can be used in coal gas, natural gas, liquefied petroleum gas, liquefied petroleum gas, nitrogen and other industrial gas pressure adjustment. Shanghai Yihuan flow control equipment Co.,ltd produced regulator can also be used in oil, chemical industry, metallurgy, pharmacy, etc.industrial departments process pressure differential, balanced system automatic regulation.
