Main Features: The turning center of the butterfly plate is on the center line of the valve body and the sealing face section of the butterfly plate. In closing, the ex-circle sealing face of the butterfly plate will extrude the valve seat made of synthetic rubber, generating elastic deformation...
The main characteristics:
1. Minimized operating torque, energy saving.
2. Small in size and light in weight...Easy installation and maintenance. It can be mounted wherever needed.
3. Simple and compact construction, quick 90 degree on-off operation.
4. Flow cure tending to straight line. Excellent regulation performance.
5. Long service life. Standing the test of tens of thousands opening/closing operations.
6. Bubbles-tight sealing with no leakage under the pressure test.
7. Wide selections of materials, applicable for various medium
8. Stem and disc are connected by means of pinless structure with more reliable performance.
9. Disc seat and body of non backed slim-disc butterfly valve are connected by frameless structure to overcome leakage on the connecting position of flange sealing surface.
