rapid open-close, frequent operation.
2, Zero leakage in air test. Good sealing in bi-directional.
3, Easy dismantle and maintenance. Suitable for both vertical and horizontal installation.
4, Simple structure, small volume and light weight. Sensitive and adjustment in 0-90 degree.
5, Various materials suits to various working medium and working conditions.
6, Simple and compact structure, low operation torque, light weight and labor saving, rapid
open-close in 0-90 degree return.
7, Straight line flow characteristics. Optimum regulating performance.
8, The open & close test up to 10 thousands times and provides long service life.
9, A variety of operating mechanisms, such as electric, pneumatic and hydraulic suits to remote and
program control up on request.
10, It can be served as gate valve, globe valve, plug valve, rubber tube valve and diaphragm valve
etc.
