Feature：
1. With eccentric body, disc, seat, can make reliable sealing.
2. long durability, the seat and disc keep apart fully when the valve open, so the sealing faces are not easy from friction.
3. with relativeky samll volume, compact structure, easy to install and maintain.
4. flow curve tending to straight line, excellent regulation performance.
5. Wrong operation prevention, locking devices optional.
6. the actuator have hydraulic, pneumatic and electric selections for long-distance control, available for computer programmable control.
