Self Operated Carbon Steel Pressure Regulating Valve

Self-operated carbon steel pressure regulating valve is a kind of can be widely used in the field of industrial regulation valve, its main function is to control the flow and pressure of the medium, to achieve the stability of the pressure system. The working principle of self-reliant carbon steel pressure regulating valve is to use the pressure of the medium acting on the spool and spring, making the spool move up or down, so as to change the flow and pressure of the medium, to achieve the stable regulation of the pressure system.
