Specification :

The wafer type butterfly valves are widely used in water supply and drainage, hydre/ thermal power, building project as well as industrial water system, such as steel and petrochemical.

Here is the features:
1. Structure simple is compact, stable positioning, and the weight is light.
2. Designs reasonably, the assembling and dismantling and installation is easy, to be advantageous.
3. Minimized operating torque. Lever, gear, pneumatic and electric actuators can be chosen.
3. Rubber backed seat with stable valve torque. No leakage under the rated pressure.
4. Special design, high flow rate and low flow resistance.
