Solenoid valve has energy storage characteristics

What is a solenoid valve?

Solenoid valves (SVs) are electrically controlled electromechanical devices used to govern the flow of liquids or gases . Solenoid valve converts electrical energy into mechanical motion or mechanical energy . The schematic representation of the SV cross-section (axisymmetric) is shown in Fig. 1.

What is a high-speed on/off solenoid valve?

High-speed on/off solenoid valves (HSVs) are digital vales commonly used in hydraulic power systems. These valves are usually used in pressure and flow control which requires high dynamic and energy performance to improve the control accuracy.

What determines the performance of a solenoid valve?

The switching speed of HSV is the main mark to determine the performance of valve. Therefore, the response characteristics of solenoid valve are so significant that it is necessary to investigate the relevant factors such as firing current and maintain current (as shown in Fig. 13 ).

Why is heat build-up a problem in a solenoid valve?

Heat build-up is another issue that has hampered effective, energy-efficient solenoid operation. This paper covers the basic operation of solenoid valves, including useful techniques and technology for optimizing performance, power consumption, and cost of operation, in either AC or DC powered applications.

Why is reliability and performance of solenoid valve important?

Reliability and performance of solenoid valve contribute for its safe operation. Remaining useful life prediction of solenoid valve helps to prevent its failure. Performance of coil insulation is critical for functioning of a solenoid valve. Solenoid valves play a key role in hybrid electric vehicles and industry 4.0.

How reliable is a solenoid valve?

Reliability of a solenoid valve, during its operation in domestic, automotive or other industrial fields, is of utmost importance for the safe functioning of it and its interconnected systems.
