Fully-Welded Ball Valve
Product Description
The ball of the floating ball valve is freely supported on the sealing ring. Under the action of fluid pressure, it is closely connected with the downstream sealing ring to form the downstream turbulent single-side seal.It is suitable for small caliber occasions.
Fixed ball ball valve ball with up and down rotating shaft, is fixed in the ball bearing, therefore, the ball is fixed, but the sealing ring is floating, the sealing ring with spring and fluid thrust pressure to the ball, the upstream end of the seal.Used for high pressure and large caliber applications.
The driving part of the valve according to the valve structure and user requirements, using handle, turbine, electric, pneumatic, etc., can be based on the actual situation and user requirements to choose the appropriate driving mode.
This series of ball valve products according to the situation of medium and pipeline, and the different requirements of users, design of fire prevention, anti-static, such as structure, resistance to high temperature and low temperature can ensure valve under different conditions are often work, widely used in natural gas, oil, chemical industry, metallurgy, urban construction, environmental protection, pharmaceutical, food and other industries.
