VA7000 series valve driverDetailed product description：

The VA7000 series valve driver can also be used with VB-7000 series valves through different connectors and other valves.

Working Principle
The driver is driven by a reversible synchronous motor and equipped with a magnetic clutch. The motor can generate stable torque even when stopped due to the magnetic interaction between the motor rotor and clutch. Therefore, when the motor is equipped with current passing through it, it can stably stop at any point. When the valve is fully opened or fully closed, the magnetic clutch disengages and stops adjusting. The signal sent by the incremental or proportional controller of the driver can cause the motor to rotate clockwise or counterclockwise.
