CH series actuator electric ball valve

The CH series actuator can directly receive 4~20mADC or 1~5VDC control signals from the computer or industrial instrument, 220VAC power supply, and intelligent step adjustment of the actuator drive motor according to the deviation of the valve position feedback signal and the set value (PID) Adjust) to achieve accurate positioning of the valve or other device with the actuator, and output the position feedback signal of 4 ~ 20mADC. Its core control component electronic servo controller is designed with modern digital technology and designed for DCS/PLC specification, integrating signal acquisition, processing, feedback and control. The original electronic brake circuit is added and the mechanical damping device is added to eliminate the inertia, which can be stopped instantaneously, without oscillation during positioning, and the positioning accuracy can reach 0.3% or more. SCR output, fast action time, stable output and high reliability. Small size, light and cheap, reliable performance, simple matching, large circulation capacity, especially suitable for occasions where the medium is viscous, containing particles and fiber properties. At present, the valve is widely used in industrial control factors of food, environmental protection, light industry, petroleum, paper, chemical, teaching and research equipment, power and other industries.
