1. Since the working pressure of china Vacuum magnetic valve equipment equipment is in a vacuum state, it cannot be started with pressure, so only direct-acting solenoid valves can be used, while ordinary solenoid valves use pilot solenoid valves when there is a pressure difference;

　　2. Vacuum solenoid valves have very high requirements on leakage. Therefore, the sealing method cannot be sealed by gaps, and the high sealing of the connection should be ensured;

　　3. The air flow sequence of China Vacuum magnetic valve equipment equipment is reverse flow state;

　　4. Vacuum solenoid valves generally use stainless steel as the production material, while there is no requirement for the valve body material of ordinary solenoid valves.
