Q941f electric flange ball valve is suitable for two position cut-off and adjustment. The connection between the valve and the actuator adopts the direct connection method. The electric actuator has a built-in servo system, and there is no need to configure another servo amplifier. The operation can be controlled by inputting 4-20mA signal and 220VAC power supply. It has the advantages of simple connection, compact structure, small size, light weight, small resistance, stable and reliable action, etc. The actuator can be equipped with UNIC, PSQ, HQ, DHL and other electronic electric actuators or GTX, Al and other gas piston actuators according to user requirements.

Ch actuator can directly receive 4 ~ 20mADC or 1 ~ 5VDC control signals output by computers or industrial instruments, 220VAC power supply, and carry out intelligent step adjustment (PID adjustment) on the actuator drive motor according to the deviation between the valve position feedback signal and the set value, so as to realize the precise positioning of the opening of valves or other devices matched with the actuator, and output 4 ~ 20mADC position feedback signals at the same time. The electronic servo controller, its core control component, is designed according to the dcs/plc specification by applying modern digital technology, and integrates signal acquisition, processing, feedback and control. The original electronic braking circuit and mechanical damping device are used to eliminate inertia, which can stop the machine instantaneously without oscillation during positioning, and the positioning accuracy can reach more than 0.3%. SCR output, fast action time, stable output and high reliability. Small size, light and pleasant, reliable performance, simple matching, large circulation capacity, especially suitable for occasions where the medium is viscous, containing particles and fibers. At present, the valve is widely used in the industrial control coefficient of food, environmental protection, light industry, petroleum, paper making, chemical industry, teaching and scientific research equipment, electric power and other industries.
