VA-7000 Linear Valve Actuator
Product Introduction
VA-7000 series drivers can provide floating point control and proportional integral control to adjust the flow of media, and are widely used in heating, ventilation, air conditioning and building automation systems. Adopting intelligent chip control, they can adapt to the valve stroke with low noise. The die-cast aluminum alloy bracket is lightweight and easy to transport and install. A bidirectional synchronous motor is used; when reaching the limit position, the spring displacement pushes the limit switch to cut off the motor power, so as to protect the motor, with high control accuracy and fast response speed.
Technical Parameters
- Low AC voltage bidirectional synchronous motor
- With learning function, automatically memorizes stroke parameters
- Accepts DC0-10V, DC2-10V or DC0-20mA, DC4-20mA control signal input for proportional control; provides DC0-10V feedback signal output to feed back the opening or closing position of the valve
- Fast working state conversion, convenient and quick for installation and debugging
- With manual open and close function (limited to VA7XXX-S type)
