Desulfurization stainless steel butterfly valve structural design essentials 1. Butterfly valve operating mechanism selection of flexible;
2. The appearance of the butterfly valve is excellent in corrosion resistance.
3. The butterfly valve adopts the midline type structure with no eccentric design, which has the characteristic of low operating torque, and the economical efficiency when configuring the electric device;
4. Reasonable design, compact structure, simple installation and disassembly, easy maintenance;
5.Using rubber-lined structure, the butterfly plate's circumferential sealing surface is precision machined to a higher finish, the friction coefficient to the rubber seat is extremely low, and the service life of the valve is longer;
6. The flow state of the valve plate sealing surface is in a linear state with a small flow resistance coefficient, and the flow resistance of the valve is small;
7. Desulfurized stainless steel butterfly valve uniquely designed molded rubber seat has excellent balance and support, effectively avoid the damage caused by uneven force of the rubber, the valve at the fully closed position, the rubber is in an excellent compression state Keep zero leakage;
8. The two-port rubber sealing surface of the valve protrudes from the nodular cast iron flange surface. The valve does not require an extra rubber gasket when installing the pipe.
