Structural characteristics
1. eccentric design makes friction free transmission between the sealing surfaces extend the service life of the valve.
2. elastic seal is generated by torque.
3. The clever wedge design makes the valve more closed and tighter automatic sealing function. The sealing surfaces are compensatory and zero leakage.
4. small size, light weight, easy operation and easy installation.
5. pneumatic and electric devices can be configured to meet the needs of remote control and program control.
