Multi turn small electric valve actuator accurate valve positioning 24V DC

Multi turn small electric valve actuator accurate valve positioning 24V DC

Non-invasive F-DZW Series multi-turn electric valve actuators are electric valve drive for controlling the valve opening and closing. For gate valves, globe valves, throttle valves, diaphragm valves, which can accurately control the movement command, is the valve to achieve remote control, central control and automatic control of the best drive. This series not only for power stations, can also be used in petrochemical, metallurgy, public utilities and so on.

Feature
 1. Non-invasive, in situ operation of the device using non-contact sensing element.
 2. Man-machine interface, high brightness, high contrast display, English menu, user-friendly setup and debugging.
 3. Infrared remote control, infrared remote control can be installed on the special position of the actuator for commissioning, operation or parameter settings and queries.
 4. Precise positioning, accurate valve positioning. Digital sensors for precise valve position monitoring.
 5. Control mode, a variety of remote control for users, both internal remote control signals to achieve electrical isolation.
 6. Signal free configuration, up to 4 contact signal output for the user to choose, each channel signal can be freely defined.
 7. Automatic phase sequence correction, the implementing agency to be free to set the rotation, CPU power can automatically correct phase sequence, regardless of when wiring the power phase sequence.
 8. Phase protection, CPU has a power phase and output phase loss protection.
 9. Fault diagnosis, internal CPU constantly implementing agency to collect a variety of information, monitor the operational status of the implementing agencies, through the issue of self-diagnostic alarm and fault information, even if the user to quickly deal with failure.
 10. Emergency operation, priority response "emergency" switch in the input signal, once effective, the implementing agency emergency operation to pre-set position.
 11. Convenient debugging, just set the record open and close direction of the terminal location, commissioning work to complete
