Electric control valve

The electric on-off valve controls the opening and closing of the main valve through the three-way solenoid valve, so as to control the on-off of the pipeline.

When the water inlet is connected with the main valve cover through the three-way solenoid valve, the main valve cover cavity will be filled with water and the main valve will be closed at the same time. When the three-way solenoid valve connects the drain port and the main valve cover cavity, the main valve cover cavity drains water and the main valve opens at the same time.

Installation precautions:

1 in the upstream side of the control valve, it is necessary to install a filter to ensure that the water quality passing through the control valve is clean

2 in the downstream side of the control valve, the exhaust valve should be installed to remove the mixed gas in the pipeline

3. When the control valve is installed horizontally, the maximum tilt angle of the control valve shall not exceed 45 degrees

4. When the control valve is installed vertically, colaval company must be informed to purchase the corresponding spring accessories (optional parts)
