The Q911F electric screw ball valve is designed for two-way shut-off and regulation applications. It features a direct connection system between the valve and the actuator, eliminating the need for an external servo amplifier. This valve can be controlled using a 4-20mA signal input and a 220VAC power supply. Its compact design, lightweight structure, low resistance, and stable performance make it ideal for various industrial environments. The actuator can be customized to suit different user requirements, including electronic models such as UNIC, PSQ, HQ, DHL, or pneumatic options like GTX, AL.

The CH series actuators are capable of directly receiving signals from computers or industrial instruments, such as 4~20mADC or 1~5VDC control signals, along with a 220VAC power supply. Based on the valve position feedback and setpoint error, the actuator drives the motor for intelligent step adjustment (PID control), ensuring accurate positioning of the valve or other components. It also provides a 4~20mADC position feedback signal. The core control unit employs modern digital technology, integrating DCS/PLC specifications for signal acquisition, processing, feedback, and control. With an original electronic braking circuit and mechanical damping, it stops instantly without oscillation during positioning, achieving a positioning accuracy of over 0.3%. The SCR output ensures fast action time, stability, and high reliability. Its compact size, light weight, and reliable performance make it suitable for thick media, particle-laden, and fibrous environments. This valve is widely used in industries such as food, environmental protection, light industry, petroleum, papermaking, chemicals, teaching equipment, and electricity.
