V230 Pressure Regulating Valve product description:

V230 Pressure Regulating Valve produced and sold by Baigang valve group,It is composed of valve body, valve seat, valve core parts and other components. It is an energy-saving product that automatically adjusts the pressure without external energy and only depends on the pressure change of the medium itself to be adjusted. It can be used as a pressure control device for non-corrosive (Max temperature 350℃) liquid, gas and steam and other media.Widely used in petroleum, chemical, metallurgy, light industry and other industrial sectors and city heating, heating system.
