What is the difference between Shijiazhuang electric wafer butterfly valve and electric double position butterfly valve? If the electric butterfly valve can not reverse normally under the rated voltage, check whether the connector (plug) of the solenoid coil is loose or not in contact. The method is to unplug the plug and measure the resistance of the coil. If the resistance is too large or too small, the solenoid coil is damaged and should be replaced.
、 4. Operation and use
1) Before operation, it must be acknowledged that pipelines and valves have been washed.
2) The operation of the valve drives the valve rod to rotate and complete according to the size of the input signal of the actuator: when the valve rotates 1/4 circle (90 °) in the positive direction, the valve is closed. When the valve is rotated 1/4 turn (90 °) in the opposite direction, the valve is open.
3) When the direction indicating arrow of the actuator is parallel to the pipeline, the valve is open; When the arrow is straight with the pipeline, the valve is closed.
2. The repair has a long service life and repair free period, which will depend on the following elements: normal working conditions, temperature/pressure ratio for consistent reconciliation, and reasonable corrosion data
