Direct Acting Solenoid Valves (DASVs) are crucial components in various fluid control systems, particularly in applications where precise, rapid control of flow is needed. Unlike other types of solenoid valves, such as pilot-operated valves, DASVs use the electromagnetic force directly to open and close the valve without the need for an auxiliary pressure source. This characteristic makes them particularly useful in specific industries and systems that require quick and reliable control over fluids and gases.
Functioning of Direct Acting Solenoid Valve The core function of a Direct Acting Solenoid Valve revolves around the principle of electromagnetism. The valve consists of a solenoid coil, which generates a magnetic field when an electric current passes through it. This magnetic field either attracts or repels the valve plunger or the valve’s internal mechanism, thus controlling the flow of fluid or gas. When the solenoid coil is energized, it creates a magnetic field that pulls the valve’s plunger away from its seat, opening the valve and allowing the fluid or gas to flow through. Conversely, when the electrical current is turned off, the plunger returns to its seated position due to the action of a spring or gravity, closing the valve and halting the flow.
