Product details
Overview of Electric Vacuum Ball Valve:
GUDElectric vacuum ball valve is a valve used in vacuum pipeline systems with zero or negative working pressure, mainly used to cut off, connect or regulate air flow. The electric vacuum ball valve can not only work normally in vacuum, negative pressure, and zero pressure states, but also be used in low-pressure states, and there are no requirements for the installation position. The relevant parts of the electric vacuum ball valve have been sealed and strengthened, such as the valve packing, flange connection, and valve body and valve cover connection, to prevent impurities from the atmospheric environment from entering the valve cavity and contaminating the medium.

Characteristics of electric vacuum ball valve:
1. The sealing structure design of the electric high vacuum ball valve is unique, which can be applied in negative pressure places and can also be used in low-pressure conditions;
2. Using an electric device to drive the valve, the opening and closing torque is small, the switch is lightweight, and the working performance is reliable;
3. The electric high vacuum ball valve has undergone special sealing treatment to ensure high sealing at the flange connection and the compactness of the structure and gasket material;
3. The leakage rate can reach<1 × 10-10Pa M3/S， Changed the current situation where ball valves cannot meet high and ultra-high vacuum requirements;
4. The electric negative pressure ball valve has a full channel core and pipeline, which can meet vacuum requirements and is also suitable for accelerator vacuum systems.

Principle of electric vacuum ball valve:
Electric vacuum ball valve is driven by the power supply pressure of the electric actuator to open and close the valve, which drives the ball core to rotate by -90 ° to achieve the connection or disconnection of the medium in the vacuum system. The opening size of the ball core can also be controlled according to the needs, so as to accurately adjust the various parameters of the medium in the pipeline system in a proportional manner. Electric high vacuum ball valves can be widely used in vacuum, food, alcohol, biotechnology, pharmaceuticals, beverages and other fields.
