High Performance V Ball Valve

Short Description:

The valve plug of the high performance V ball valve is a V ball, which is a kind of rotary control valve that controls fluid flow through changing the V cut area. It is especially suitable for controlling media containing fibers or granules, such as control in applications such as paper pulp production, sewage treatment, oil product pressure stabilizing oil transportation pipeline, etc. The plug is provided with the rotary shaft at the upper and lower ends. The seat is provided with the booster ring for controlling the sealing force. When the valve is opened or closed, the V cut produces wedge shearing force with the seat, so that the sealing performance is superior to that of O ball valve, gate valve, etc. It is mainly applied in such industries as petrochemical industry, paper & pulp, light industry, water treatment, etc.

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 to shut off media containing fibers. It is especially suitable for opening and controlling media of high viscosity and media containing fibers and granules.
