Regulating valves are composed of three major departments or a combination of three major technologies, with the key component being the servo measurement and control box completed by electronic information technology. The actuator manufactured by electromechanical technology is also important. Pure mechanical processing regulating valves have also made many breakthroughs in recent times, and ultra light regulating valves are one of them. They have won the trust of the market for their compact structure, small volume, light weight, large flow coefficient, good sealing performance, and large allowable pressure difference.
