It is a kind of right angle rotary adjusting valve , made up of ZSH pneumatic piston actuator and V-type ball valve, with soft sealing and metal hard sealing types. Because of its right angle rotary structure, with high cut-off function when valve spool rotate related to valve seat, specifically suitable for fibers and small particles regulating. Widely used in oil、chemical、power、paper、metallurgy industries.

Features :

V-ball valve ,simple flow path, small flow resistance and therefore greater flow capacity.

Adjustable ratio up to 300:1, is much greater than through single-seat control valve.

With high sealing level: leakage level of soft sealing structure: GB/T　4213　Ⅵ; leakage level of hard sealing structure : GB/T　4213　Ⅳ

Convenient switching of positive, reactive way, just rotate 90º of initial position of valve spool .

Simple structure、convenient maintenance, small size 、easy to install
