Ball valve in the pipeline is mainly used for cutting, distribution and change the direction of flow of media, it only needs to rotate 90 degrees of operation and a small rotation torque can close tight. The most suitable valve to do the switch, cut off the valve to use, V-type ball valve. In addition to attention should be paid to the electric valve valve parameters, should pay special attention to the use of environmental conditions, the electric valve in the electric device is an electromechanical equipment, its use by its use of environmental impact. Under normal circumstances, electric ball valve, butterfly valve in the following environment to use special attention.
2;Good sealing performance:as a result of hard sealed ball valve sealing is the use of artificial grinding, until the valve core and the ring can be used in full compliance. So his sealing performance is reliable.
3;Switch light:as a result of hard sealing ball valve seal at the bottom of the spring and the spool to hold tightly together, so the outside force exceeds the spring preload when the switch is very light.
4;Long service life: has been widely used in petroleum, chemical, power generation, paper, atomic energy, aviation, rockets and other departments, and people's daily lives.
