    3-Way 2-Position Solenoid Valve NC SymbolTips: Differences between pilot-operated and direct acting solenoid valve

    1. Pressure tolerance
    The pilot-operated solenoid valve has a higher tolerance of liquid pressure than the direct acting solenoid valve.

    2. Response time
    The starting speed of the direct acting solenoid valve is quicker than that of the directly operated type. It is mostly used for the occasion of fast connection and disconnection. Because the small valve opens in the first and the main valve opens later when the pilot-operated solenoid valve is supplied with power. Instead, the directly operated solenoid valve is opened with its main valve directly. When the pilot-operated solenoid valve is energized, the small valve opens at the first and the main valve opens later. However, as to the direct acting solenoid valve, the main solenoid opens directly.

    3. Flow capacity
    The flow capacity of the pilot-operated solenoid valve is bigger than that of the directly operated type. Generally, the CV value can reach 3 or above.

    4. Power and consumption
    The power and consumption of the directly operated solenoid valve are higher than that of the pilot-operated type.

    5. Purity of the medium
    The pilot-operated solenoid valve has a relatively high requirement to the purity of the flowing medium. However, the direct acting type has no such strict requirement.

    Pressure range of pneumatic solenoid valve
    For your pneumatic solenoid alve, what is the nominal pressure range it can work at and can it work in vacuum systems?

    ATO Responded
    1. Nominal pressure range: 0.15~0.8MPa (22~116 psi).
    2. There is no solenoid valve that works in vacuum.
    The valve worked great.
    I bought this to replace the broken one for the air locker. The valve worked great…thank you.
