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 t...

Products Design Features
Gate valve is one of the most commonly used cut-off valves, it*s mainly used to connect and disconnect media in pipe. The range of suitable pressure, temperature and caliber is very wide. It is widely used in water supply and drainage, gas, electric power, petroleum, chemical industry, metallurgy and other industrial pipeline which media is steam, water, oil to cut off or adjust the flow of media.
Main Structural Features
Fluid resistance is small.
It is more labor-sa...
Product Overview
DIN ball valve adopts split structure design, good sealing performance, not limited by the direction of installation, the flow of the medium can be arbitrary;There is an anti-static device between the sphere and the sphere;Valve stem explosion-proof design;Automatic compression packing design, fluid resistance is small;Japanese standard ball valve itself, compact structure, reliable sealing, simple structure, convenient maintenance, sealing surface and the spherical often in ...
