product manual:
Q947F electric fixed ball valve is a new generation of high-performance ball valve, suitable for long distance pipelines and general industrial pipeline, its strength, safety, resistance to harsh environments, etc. are designed for a special consideration for a variety of corrosive and non-corrosive media. Compared with the floating ball, work, force the valve before the fluid pressure on the ball is passed to produce all the bearings, so that the ball does not move to the seat, so the seat does not put too much pressure, so fixed ball valve torque is small, seat deformation, stable sealing performance, long life, suitable for high pressure, large diameter occasions. Advanced spring pre-seat assembly, with self-tightening properties upstream seal achieve. Each valve has two seats in each direction can be sealed, thus installation is flowing not limited.
 
working principle:
    Q947F electric valve is fixed supply voltage for power, acceptance of (4-20mA, 0-10mA or 1-5VDC) current or voltage signals, to control operation to rotary output torque to rotate the sphere 0 ~ 90 °, on to complete the opening and closing action or regulatory action. Full electronic actuators, adopt a mechatronics structure, with machine operation and opening signal servo position feedback, position indicator, manual operation and other functions, powerful, reliable performance, simple connection, via the input current or voltage signal signal, changing ball core rotation angle (0-90 ° at any angle) to achieve proportional control action.
