Segmented ball valve

Segmented ball valve introduction

Segmented ball valve belongs to trunnion mounted ball valve, Segmented ball valve is also a single seat sealing ball valve, regulating performance is the best ball valve, flow characteristics is equal percentage, adjustable ratio up to 100:1.Segmented ball valve V-shape cur port and metal seat between shear action, especially suitable for containing fiber, micro solid particles, slurry and other media.
 

Segmented ball valve overview

Segmented ball valve has the same rotation action of 90 degrees, except that the cock body is a ball with a circular through hole or channel through its axis.The segmented ball valve in the pipeline is mainly used to cut off, distribution and change the flow direction of the medium, it only needs to use a rotation of 90 degrees of operation and a small torque to close tight.Segmented ball valve is best suited for use as switch and shut-off valves, but in recent development, segmented ball valve have been designed for throttling and flow control.
 

Segmented ball valve working principle

Segmented ball valve is a kind of high performance V-type control valve with V-type core structure. V-type opening of segmented ball valve can form various V-type angles with the valve seat flow passage to realize the precise proportional regulation of various parameters of pipeline media.When the electric V-type regulating segmented ball valve is closed, the V-type incision can easily cut off the various pulp or fiber in the pipe and other viscous medium, effectively ensure the circulation of the pipeline, but also prevent the phenomenon of the segmented ball valve ball core stuck.V-ball valves have approximately equal percentage or linear flow characteristics for regulating flow, and V-port angle of Segmented ball valve can be customized to meet more accurate cutoff characteristics and control functions.
Segmented ball valve ball core with V-type structure, the segmented ball valve core is a quarter of the ball shell, v-type notch, large flow capacity, adjustable range, shear force, can close tight and other characteristics, especially suitable for fluid material with fiber conditions.Under normal circumstances are single seal ball valves, not suitable for two-way use.
  

Segmented ball valve feature

1. Integrated body structure of segmented ball valve: sandwich type and flange Type V ball Segmented ball valve body installed on the side of the structure, rigid structure, not deformation and leakage.
2. Self-lubricating bearing of segmented ball valve: The oil plate adopts self-lubricating bearing, which has the characteristics of large total contact area of the valve stem, large bearing capacity, small friction resistance and small torque of the Segmented ball valve.
3. Hard seal or PTFE soft seal of metal composite material for segmented ball valve can be selected according to chemical substance and condition.Spray welding cemented carbide tool on the sealing surface of metal hard sealing seat to implement hard chrome surface coating,chrome plating, ion nitridation and other hard substrate solutions to improve the service life of protruded surface, improve segmented ball valve temperature resistance.
4. Economical and practical of segmented ball valve: segmented ball valve is light weight of valve body, small torque of valve shaft, small specifications with air and electric actuator, more cost-effective than other types of control valves.
5. Wide range of media of segmented ball valve: due to the shear force between the V-shaped opening and the seat and the smooth roundness of the valve cavity flow, the medium is difficult to stay in the inner cavity. Therefore, in addition to the liquid medium, segmented ball valve is also suitable for the system control of fiber and solid particle media.
6. Low flow precision control of segmented ball valve: By machining the special V-shaped opening of the small-diameter segmented ball valve body, the low flow precision control can be realized.
