High Performance V Ball Valve

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.
