How to choose according to different job needs?
1. When the solenoid valve needs to be closed for a long time and the closing time is longer than the opening time, the normally closed type is selected.
2. When the solenoid valve needs to be opened for a long time and the opening time is longer than the closing time, select the normally open type.
3.When it is necessary to turn on for a long time and close it for a long time, select the normally open normally closed type.
4.Some conditions for safety protection, such as furnace flame monitoring, can not be selected for normal opening, should be selected for long-term energization type
How to judge whether the coil is working or burned out?
1. Measure the resistance. If the resistance is 0 or infinite, the coil is short-circuited or burned out.
2. Take the iron screwdriver without magnetic, close to the nut on the coil. If there is magnetic adsorption after the coil is energized, the coil will work normally.
