v230 pressure regulating valve product description:
v230 pressure regulating valve produced and sold by woci 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.
