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 ...
Summary
The V cut has large adjustable ratio and equal percentage flow characteristic, realizing stable control of pressure and flow.
Simple structure, small volume, light weight, smooth flow channel.
Provided wrth large nut elastic automatic compensation structure to effectively control the sealing face of seat and plug and realize good sealing performance. The eccentric plug and seat structure can reduce wear.
The V cut produces wedge shearing force wrth the seat t...
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...

Summary
The eccentric ball valve adopts the movable valve seat structure loaded by leaf spring, the valve seat and the ball will not have problems such as jamming or separation, the sealing is reliable, and the service life is long, The ball core with V-notch and the metal valve seat have shear effect, which is especially suitable for the medium containing fiber, small solid partides and slurry. It is particularly advantageous to control the pulp in the papermaking industry. The V-notch struc...
