Introduction
The solenoid coil is the key component of a hydraulic valve. Sometimes, the solenoid valve can be broken due to various reasons. This article will analyze all the possible reasons and how to tackle with them.
Tools
-
-
Test the solenoid with a multi-meter, if the resistance is close to zero or infinity, it means that solenoid is either open circuit or broken circuit.
-
If open circuit or broken circuit happens, you need to change a new solenoid coil.
-
-
-
If there is a plug on the solenoid valve, you may need to check the metal spring clip inside the socket.
-
If this problem happens, modify the wire connection, repair or replace the plug or socket.
-
-
-
The valve element can be problematic because of too much water in the compressed air or too many foreign particles in the liquid medium.
-
Check the valve element and get rid of all the foreign matters.
-
If problem still occurs, replace the full valve element.
-
-
-
bad wiring. Re-connect the wire.
-
Regulate voltage to the normal range.
-
weld the solenoid coil again.
-
regulate the pressure differences.
-
-
-
replace the sealing parts of broken valve element
-
replace the solenoid valve with a suitable one for medium with a higher temperature.
-
clean the foreign matters in the valve element.
-
To reassemble your device, follow these instructions in reverse order.
