Are Solenoids Valves Supposed to Get Hot?

Resolution: It is normal for a solenoid to be warm to the touch. Resolution: Various situations, such as continuous duty use or application of voltage that is higher than specified, can cause the solenoid to become warm.

Is it normal for solenoid valve to get hot?

When a solenoid is first energized, its coil receives a pulse of high inrush current that decreases as the plunger closes. If the plunger does not close, the high inrush current continues, which can cause the coil to overheat and burn out. ... Thus, a solenoid too hot to touch may not be overheated.

How hot should a solenoid valve get?

A solenoid typically has a temperature rise (internally) of between 65° C (approx. 150° F) to 105° C (approx. 212° F). If there is a problem within the valve (such as a jammed piston), the coil would burn out and heat would no longer be generated.
