Product description :
Brass ball valve in the pipeline is mainly used to cut off the fluid, distribution and change the direction of the flow of media, designed into a V shape of the ball valve also has a good flow control function.
Design principle :
Brass ball valve is evolved from the cock, its opening and closing parts as a ball, the ball around the axis of the stem rotation 90o to achieve the purpose of opening and closing.
Characteristic:
- Good sealing performance, small fluid resistance.
- Suitable for regular operation, open and close quickly and easily.
- The utility model has the advantages of simple structure, relatively small size, light weight and convenient maintenance.
- Not limited by the installation direction, the flow of media can be arbitrary.
- The inner channel of the valve body is smooth and smooth, and can be used for conveying viscous fluid, slurry and solid particles.
- The fluid resistance is small, the valve is in a fluid resistance all Farey minimal, even reduced diameter valve, the fluid resistance is quite small.
- Fast switching speed, convenient, as long as the turning of the stem 90o, completes the valve fully open or fully closed operation, it is easy to achieve rapid opening and closing.
