First, the electric two-way valve working principle The
 drive is driven by a reversible synchronous motor, and with a magnetic clutch. The motor produces a magnetic effect through the motor rotor and the clutch, producing a steady torque when stopped. Therefore, when the motor is no current can stably stop at any point, when the valve is fully open or fully closed when the magnetic clutch, stop adjusting. The signals from the drive's incremental or proportional controls enable the motor to rotate clockwise or counterclockwise.

Second, the electric valve features
 24V AC voltage reversible reversible motor. 1000 Newton force. Limit magnetic clutch. Movement using gear transmission, the output gear screw group rotates around the central axis of the plane rolling bearings, the valve shaft is the use of the central screw pipe and the positioning of the wafer. Valve actuator position indicator. Fire-proof ABS plastic cover. Can be attached to the manual lever. Site installation easy. Suitable for direct stroke valve below 23mm.

1, the actuator used cast aluminum bracket and plastic shell, small size, light weight.  
 2, the choice of permanent magnet synchronous motor, and with a hysteresis clutch mechanism, with reliable self-protection.  
 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, transmission gear with metal gears, greatly improving the service life of the drive.  
 6, low power consumption, output power, noise.  
 7, the valve body cast copper, cast iron, ductile iron a variety of materials to choose from, in order to suit different working media and temperature requirements. 
 8, the valve body has two threaded connections and flanges, easy to install.  
 9, the body structure of the form: two-way valve (single seat), two-way balance valve (balanced).
 

Third, the main electric two-way valve connection size
