Note one
For pilot-operated solenoid valves, it is necessary to check whether the pressure difference in the pipeline is too small. If the pressure difference is too small, the
solenoid valve cannot work normally. In this case, a direct-acting solenoid valve is required. And the pressure difference is too large, far exceeding the design value of the solenoid valve, and it cannot work normally, so a high-pressure solenoid valve should be used.
Note two
The solenoid valve is generally installed horizontally. If the pepper is installed on the side, it may cause the valve to not close tightly, that is, internal leakage, because try to avoid side installation.
Note three
When used for a long time, if the seal between the piston and the valve seat is not good, the sealing surface of the piston can be re-ground, and then ground with the valve seat.
Note four
When working, pay attention to the pressure gauges before and after the valve. It is required that the working pressure should not exceed the rated pressure, and the working pressure difference must be within the rated pressure difference range. When the working pressure exceeds the rated pressure or the working pressure difference exceeds the rated pressure difference, the solenoid valve should be stopped, and the front and rear manual valves should be closed to prevent the solenoid valve from exploding and leaking.
Note five
After the solenoid valve is installed, it is necessary to pass the medium to test several times, and then it can be put into official use after confirming that it is normal.
Note six
The dirt inside and outside the large valve and the armature suction surface should be cleaned regularly. Be careful not to damage the sealing surfaces.
Note seven
When the solenoid valve is not used for a long time, the manual valve in front of the valve should be closed. When it is reactivated, the steam solenoid valve should drain the condensed water, and make test actions several times, and then put it into use after the switch is normal.
