Direct acting Solenoid valve

Operating Principle: Direct-acting solenoid valves work by directly opening or closing the valve using the magnetic force produced by an energized coil. The plunger or diaphragm of the valve is directly controlled by the coil.

Power Requirement: Direct-acting solenoid valves can be powered by both alternating current (AC) and direct current (DC) sources. They provide a variety of power supply choices.

Response Time: Compared to pilot-operated solenoid valves, direct-acting solenoid valves often respond more quickly. Faster opening and shutting operations are possible due to the direct mechanical connection between the coil and the valve element.

Applications: Direct-acting solenoid valves are appropriate for situations where a compact design, a quick response, and low flow rates are required.

DC solenoid valve

Operating Principle: In order to control the valveā€™s plunger or diaphragm, DC solenoid valves use the magnetic force produced by an energized coil. When energized, the coil produces a magnetic field that causes the valve element to move.

**Power Requirement:**DC solenoid valves are made specifically for DC power sources, hence they have a high power need. They frequently run at a certain voltage, like 12V or 24V DC.

Energy Efficiency: Compared to AC solenoid valves, DC solenoid valves are often more energy-efficient. They use less energy while the valve is closed since they only draw electricity when the coil is activated.

Applications: Mobile applications, battery-powered systems, and circumstances where a dedicated DC power supply is available all make use of DC solenoid valves frequently.

AC solenoid valve

Operating Principle: To control the flow of fluid or gas, AC solenoid valves use a pilot valve or a pilot valve that is solenoid-operated. The pilot valve is activated by the AC solenoid coil, and it then regulates whether the main valve element opens or closes.

Power Requirement: AC solenoid valves are made specifically for AC power sources, hence they have a high power need. They are designed to function with the alternating polarity and periodicity of the AC waveform, as well as the properties of AC current and voltage.

Wide Voltage Range: Depending on the requirements of the individual application, AC solenoid valves can function within a wide range of AC voltages, such as 110V, 220V, or 240V.

Applications: AC solenoid valves are frequently utilized in commercial and industrial settings, as well as in HVAC and water treatment systems.

In conclusion, direct-acting solenoid valves may operate with both AC and DC power sources and work by directly manipulating the valve element. Because they are made exclusively for DC power, DC solenoid valves often use less energy. Pilot valve-equipped AC solenoid valves are designed for AC power sources with a variety of voltage options.
