Self operated regulating valve

Self operated regulating valve is an automatic regulating valve that automatically adjusts the temperature, pressure, and flow rate of the pipeline inlet and outlet through pressure sensors or temperature sensors and springs. Its working principle relies on the pressure and temperature of the medium flowing through the valve as energy to drive the valve to work automatically, without the need for external power supply and secondary instruments, so it is also known as self operated control valve. The self operated regulating valves produced by Shanghai Meiyan Yi Pump Valve use feedback signals (pressure, pressure difference, temperature) from the valve output end to be transmitted through signal pipes to the actuator to drive the valve disc and change the valve opening, achieving the purpose of regulating pressure, flow rate, and temperature. Compared to manual regulating valves, its advantage is the ability to automatically adjust, while compared to electric regulating valves, its advantage is that it can easily achieve system flow distribution without the need for external power.
