CK50/CK70/CK90 series valve driverDetailed product description：

Purpose
CK50/CK70/CK90 series linear actuator (driver), suitable for use with VB series DN65~DN200 regulating valves with two-way and three-way connections.

Model Description
CK51/CK71/CK91: Floating state control.
CK52/CK72/CK92: Standard signal control, capable of accepting 0-10V or 4-20mA control signals, and providing feedback of 0-10V valve position voltage signals, providing proportional control.
Characteristics
A synchronous reversible motor with 24V AC voltage.  
Adopting a small travel switch limit.  
CK52/CK72/CK92 has a built-in digital display, making debugging more intuitive and convenient, with high control accuracy and fast response speed
Flame retardant ABS plastic cover
Can be equipped with a manual control lever.  
Easy on-site installation.  
Suitable for straight stroke regulating valves below 45mm

Working Principle
The driver is driven by a reversible synchronous motor, and the valve stem moves up or down to open and close the valve. When the valve is fully open or fully closed, a reactive force is generated on the driver, causing the internal micro switch of the driver to be powered off and the driver to stop working. When the driver receives a control signal, it can open the valve to a certain degree and stably stop at any point when there is no signal.
