DDCY-20Q is a DC solenoid vacuum pressure Valve designed for use in mechanical vacuum pumps. It is installed at the inlet of the pump and synchronizes its opening and closing with the pump operation. This valve ensures that when the pump stops or power is cut off, it automatically closes due to atmospheric pressure, maintaining the vacuum system and preventing oil backflow from contaminating the pump.

The DDCY-Q series vacuum pressure solenoid valve is ideal for applications involving air and non-corrosive gases. It is commonly used in industrial vacuum systems where reliable sealing and quick response are essential. The valve is equipped with an automatic closure mechanism that activates when the pump is not running, ensuring the vacuum system remains intact and free from contamination.
This valve is particularly useful in environments where sudden power failures may occur, as it prevents oil from flowing back into the vacuum system, which could otherwise damage the pump or reduce its efficiency. Its compact design and durable construction make it suitable for both commercial and residential applications.
**Description:**
The DDCY-Q series vacuum pressure solenoid valve is installed on dedicated mechanical vacuum pumps. It synchronizes with the pump's operation and automatically closes when the pump stops or power is lost. This helps maintain the vacuum and prevents oil backflow, ensuring the system remains clean and efficient.
