Ball Valve Technology Frontier High Efficiency Reliability And Innovation

The main structure of a ball valve includes a valve body, a ball, a valve seat, a valve stem and an actuator. The valve body is the shell of the ball valve and is usually made of metal materials to withstand fluid pressure and support internal components. The ball is the core component of the ball valve. Its surface is precisely processed and coated to ensure good sealing performance and wear resistance. The valve seat closely cooperates with the ball to form a sealing surface to prevent fluid leakage. The valve stem connects the ball and the actuator and is used to transmit operating torque. The actuator can be manually, electrically, pneumatically or hydraulically driven. Select the appropriate driving method according to different application scenarios.

The sealing performance of the ball valve is extremely excellent and can maintain a good sealing effect under high-pressure and high-flow-rate working conditions. Its sealing principle mainly relies on the close contact between the ball and the valve seat. When the valve is closed, the ball is tightly attached to the valve seat under the action of fluid pressure to form a sealing surface. This sealing method is not only applicable to liquid media but also to gas media. Even in a vacuum environment, it can maintain good sealing performance.
