① It's upside-down
The solenoid valve cannot be installed in the reverse direction. When installing, note that the arrow on the valve body should be consistent with the flow direction of the pipeline fluid, and the coil should be installed vertically upwards and horizontally.
② card stuff
If there are impurity particles in the medium, the valve port will be stuck, causing it to be unable to close or open. Disassemble the solenoid valve, clean it, and install it again (the solenoid valve requires a relatively clean medium, if there are small impurities in the medium And dust must be installed in front of the valve with a filter provided by "our company" (filter mesh ≥80 mesh/cm2).)
③Incorrect pressure
Is pressure standard? For 0 pressure and steam, you must choose a completely direct-acting solenoid valve
