Product Description
Electric two-way valve product introduction
VB-7000 series electric two-way valve can also be used through different connectors with other valves, used for air conditioning, thermal ventilation, heat treatment plant industry and industrial fluid control.
Working principle of electric two-way valve
The drive is driven by a reversible synchronous motor and comes with a magnetic clutch. The motor can generate stable torque in the case of pause through the magnetic effect generated by the motor rotor and the clutch. Therefore, when there is no current through the motor, it can stably stop at any point, and when the valve is fully opened or fully closed, the magnetic clutch is disengaged and the adjustment is stopped. The signal from the incremental or proportional controller of the drive can make the motor rotate in time or reverse time.
Features of electric two-way valve
Synchronous reversible motor with 24V AC voltage. 1000 Newtonian power. Limit magnetic clutch. The action is transmitted by gears, the output gear screw group uses a flat rolling bearing that rotates around the central axis, and the valve shaft uses a central screw pipe and a positioning disc. Valve position indicator. Fireproof ABS plastic housing. A manual control lever can be attached. Easy installation on site. Suitable for 23mm below the straight stroke control valve.
1. The actuator is made of cast aluminum bracket and plastic shell, which is small in size and light in weight.
2. The permanent magnet synchronous motor is selected, and it has a hysteresis clutch mechanism, which has a 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 gear, which greatly improves the service life of the driver.
6. Low power consumption, large output force and low noise.
7, the valve body has cast copper, cast iron, ductile iron a variety of materials to choose from, to suit the requirements of different working media and temperature.
8. The valve body has two kinds of threaded connection and flange connection, which is easy to install.
9, the body structure: two-way valve (single seat), two-way balancing valve (balanced).
