Product features

GUD electric vacuum ball valve is a valve used in vacuum pipeline systems where the working pressure is zero pressure or negative pressure. It is mainly used to cut off, connect or regulate the air flow. The electric vacuum ball valve can not only work normally under the conditions of vacuum, negative pressure and zero pressure, but also can be used under the condition of low pressure, and the installation position is not required. Relevant parts of the electric vacuum ball valve have undergone sealing strengthening treatment, such as the packing of the valve, the flange connection and the connection of the valve body and bonnet, to prevent impurities in the atmosphere from entering the valve cavity and polluting the medium.
Features of electric vacuum ball valve:
 
1. The electric high vacuum ball valve has a unique sealing structure design, which can be used in both negative pressure places and low pressure conditions;
2. The electric device is used to drive the valve, with small opening and closing torque, light opening and closing, and reliable working performance;
3. After special sealing treatment, the electric high vacuum ball valve can ensure the high tightness of the flange connection and the compactness of the structure and gasket materials;
3. The leakage rate can reach<1 × 10-10Pa M3/S, changing the status quo that the ball valve cannot meet the requirements of high vacuum and ultra-high vacuum;
4. The electric negative pressure ball valve core and pipeline are full channels, which can meet the vacuum requirements. Gu can also be used in the accelerator vacuum system.
  
Principle of electric vacuum ball valve:
 
The electric vacuum ball valve is used to open and close the valve by driving the valve stem with the power supply pressure of the electric actuator to drive the ball core to make -- 90 ° rotation, so as to achieve the connection or shutdown of the medium in the vacuum system. The opening of the ball core can also be controlled as required, so as to carry out proportional and accurate adjustment of various parameters of the medium in the pipeline system. Electric high vacuum ball valve can be widely used in vacuum, food, alcohol, bioengineering, pharmaceutical, beverage and other fields.
