Product features of turbine wafer type desulfurization butterfly valve

 

1. The non eccentric design with medium linear structure has the characteristics of low operating torque and remarkable economy when equipped with electric device;

2. Reasonable design, compact structure, simple installation and disassembly, easy maintenance;

3. With rubber lining structure, the butterfly plate circumferential sealing surface is precision machined to a higher finish, the friction coefficient of rubber seat is low, and the valve service life is long;

4. The flow pattern of the valve plate sealing surface is linear, with small flow resistance coefficient and small valve flow resistance;

5. The designed molded rubber seat has good balance and support, which can effectively avoid the damage to rubber caused by uneven force. When the valve is fully closed, the rubber is in a good compression state to maintain zero leakage;

6. The rubber sealing surface of the two ends of the valve protrudes from the ductile iron flange surface, so there is no need for additional rubber sealing gasket when the valve is installed in the pipeline;

7. The operating mechanism of butterfly valve is flexible.
