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 Description
The opening and closing parts of J41H, J41Y, J41W GB globe valve are cylindrical disc, the sealing surface is flat or conical, and the disc moves in a straight line along the center line of the fluid.GB globe valve is only applicable to fully open and fully closed, generally not to adjust the flow, custom allowed to adjust and throttle.

Product Overview
Q47 type fixed ball valve compared with the floating ball valve, it is working, fluid pressure in front of the sphere of all is passed to the bearing force, will not make a sphere to the seat to move, so the seat will not bear too much pressure, so the fixed ball valve torque is small, the seat of the small deformation, stable sealing performance, long service life, applicable to high pressure, large diameter.Advanced spring pre - seat assembly with ...
