These valves generally operate either fully open or fully closed, although there are applications where flow is controlled in a linear fashion.Īlso, there are solenoid valves that can work with alternating current (AC) or with direct current (DC) and use different voltages and operating cycle durations, depending on their construction or shape.ĭown below are the failure modes of solenoid valves. We can use the solenoid valve to control the flow of many different fluids, giving due consideration to the following parameters in the construction of the valve. The reason for this is, it is possible to create or eliminate the magnetic field when activating or deactivating an electrical current.
Thus, the electromagnet is important for the design of automatic control. It opens by the movement of a plunger operated by the magnetic action of an electrically energized coil, or vice versa.Ī solenoid valve consists of two distinct parts, but integral actuating parts:Īn electromagnet produces lines of magnetic force when electric current flows through the coil of the electromagnet. The solenoid valve is a valve that closes by gravity, by pressure, or by the action of a spring. It controls the flow of liquids or gases in the fully open or fully closed position. What is a Solenoid Valve?Ī solenoid valve does not regulate flow. We will discuss some of the common failure modes of the solenoid valves in this article. There are various reasons for failures of solenoid valves during solenoid valve operation.
The solenoid valve is an electrically operated device. The term Common failure mode of the solenoid valve is used to refer to the different ways in which a component of the solenoid valve may fail.
