Working principle

      The driver is driven by a reversible synchronous motor with a magnetic clutch. The motor can generate stable torque in the case of a standstill through the magnetic action generated by the motor rotor and the clutch. Therefore, when there is no current through the motor, the motor can stably stop at any point. When the valve is fully opened or fully closed, the magnetic clutch is released and the adjustment is stopped. The signal from the incremental or proportional controller of the drive can make the motor rotate clockwise or counterclockwise.

Features

     Synchronous reversible motor with 24V AC voltage. 1000 Newtons. Limit magnetic clutch. The action is transmitted by gears, the output gear screw group uses a flat rolling bearing rotating around the central axis, and the valve shaft uses a central screw pipe and positioning disc. Valve position indicator. Fire-resistant ABS plastic cover. A manual control lever can be attached. Easy to install on site. Suitable for straight-stroke control valves under 23mm.

   1. The actuator is made of cast aluminum bracket and plastic shell, which is small in size and light in weight.　

   2. Use permanent magnet synchronous motor with magnetic hysteresis clutch mechanism and reliable self-protection function.　

   3. Suitable for a variety of control signals: incremental (floating point), voltage (0-10V), current (4-20mA).　

   4. With 0～10V or 4～20mA feedback signal (optional).　

   5. The transmission gear adopts metal gears, which greatly improves the service life of the driver.　

   6. Low power consumption, high output power and low noise.　

   7. The valve body is available in cast copper, cast iron, and ductile iron to meet the requirements of different working media and temperatures.

   8. The valve body has two kinds of screw connection and flange connection, which is easy to install.　

   9. The structure of the valve body includes: two-way valve (single seat) and two-way balance valve (balanced).
