Solenoid Valves 101: An In-Depth Guide to the 5 Main Types
Solenoid valves are useful and reliable components used in a variety of machines, from washing machines and gas boilers to hydraulic pumps and air hammers. Despite their dependable nature, solenoid valves are still prone to malfunction or break. It is important to know the basic types of solenoid valves and the typical problems that can arise so that repairs can be made in a timely manner.
1. Dirty or Clogged Valves: When they are used regularly, solenoid valves can become clogged with dirt, dust, or other debris. Clogging can be the result of working in dusty environments, or if the solenoid valve contains a filter, it can become clogged due to a build-up of debris over time. If a valve is clogged, it will not be able to open properly, disrupting the flow.
2. Sticking Valves: Solenoid valves can stick due to dirt and grime that accumulate in the valve core and seat or due to corrosion caused by moisture exposure. If a valve sticks, it will not open or close properly, disrupting the flow.
3. Short Circuits: When electricity is used to power a solenoid valve, a short circuit can occur that causes the valve to fail. This can be the result of a disruption in the wiring, moisture exposure, or something else.
4. Insufficient Power: If the power used to activate the solenoid valve is not powerful enough, then the valve will not open or close properly, disrupting flow. This can happen if the power supply is interrupted, or if the wiring is damaged.
Understanding the different types of solenoid valves and typical problems can help to prevent costly repairs or replacement. If you suspect that a solenoid valve is malfunctioning, then it is best to act quickly and replace it with a new one. This will ensure that your equipment remains operational and efficient.
