What are the differences between Parker pilot solenoid valve and direct acting solenoid valve?

Some users usually use the solenoid valve parker Parker is divided into pilot solenoid valve and direct acting solenoid valve , So how to partition parker Parker direct acting solenoid valve and pilot solenoid valve ？ What are the differences ？ The following is our Ningbo Sicheng to tell you more about parker Parker direct acting solenoid valve and pilot solenoid valve have five differences .

parker The difference between Parker direct acting solenoid valve and pilot operated solenoid valve ：

1. The difference in stress ： The hydraulic pressure of the pilot solenoid valve is greater than that of the straight through solenoid valve .

2. Different response times ： Compared with the pilot type solenoid valve , The direct acting solenoid valve has faster starting speed , Therefore, it is more suitable for places that need to be cut off quickly . As the pilot solenoid valve is energized, the small valve opens first , And then open the main valve , The direct acting solenoid valve directly opens the main valve .

3. Difference in circulation capacity ： The flow capacity of the pilot solenoid valve is slightly greater than that of the direct acting solenoid valve , Usually CV Greater than 3, The direct acting solenoid valve is usually CV Less than 1.

4. The difference between power and loss ： The power and loss of direct acting solenoid valve is greater than that of pilot operated solenoid valve .

5. The requirements for medium cleanliness are different ： Pilot operated solenoid valves require high purity of circulating media , The direct acting type is not too strict .
