Excessive heat may cause the coil to burn out. If the solenoid valve is part of a fluid system, check and clean the filters or strainers upstream of the valve to prevent debris from entering and causing problems. Effective troubleshooting of solenoid valves involves a systematic approach to identify and address issues.
When a Normally Closed solenoid valve isn’t receiving power, it closes and stops the gas or liquid from passing through it. When a current is applied to the coil it pushes the plunger upward against the spring force. This action unseals and opens a port allowing media to pass through the valve.
A quick and simple guide to troubleshooting your solenoid valve. The possible causes for your valve not closing correctly are listed below alongside instructions of how to resolve the issue. Lift the solenoid coil slightly (do not remove completely as an a.c. coil will burn out quickly) to feel if there is residual magnetic field.
For applications where the valve must be open for extended periods of time, a normally open solenoid valve is ideal because it uses less energy. They can also be utilised for safety purposes, in cases where the application calls for the valve to remain open and unpowered to ensure a safe operating condition.
A faulty solenoid valve cannot operate according to requirements. It may not regulate the medium in the system well, which can lead to fluid leaking through the orifice. If the valve’s function is to dose or mix liquid, it can be a disastrous situation. The same case if the valve controls functions where accuracy is paramount.
Control of the solenoid is performed by permanent magnets instead of a spring mechanism, reducing power consumption. Pilot-operated Solenoid Valves use the energy stored in the build-up of pressurised fluid or gas to power the valve's opening or closing and are either internal or external piloted.

Solar Water Heater Pressure Release Automatic Air Exhaust Valve
I fitted a solenoid valve to bypass the circulating pump so that there will be some circulation by convection, however, the temperatures still rise above 100C and the steam hammering persists. To mitigate, I fitted a relief valve to the solar flat panel water heating system at the outlet end. Please see the attached image.
