Features of rubber lined butterfly valve：
1. The design is novel, reasonable, unique in structure, light in weight and quick in opening and closing.
2. Small operating torque, convenient operation, labor saving and dexterous.
3. It can be installed in any position and easy to maintain.
4. The sealing element can be replaced, the sealing performance is reliable, and the two-way sealing is zero leakage.
5. The sealing material has the characteristics of aging resistance, corrosion resistance and long service life. Standards adopted
6. The rubber lined butterfly valve is designed and manufactured by adopting a new structural form of welding the central line type disc plate and short structure steel plate. It is compact in structure, light in weight, easy to install, small in flow resistance, large in flow capacity, easy to operate / 7, without connecting rod, bolt, etc., which is reliable and has long service life. It can be installed in multi station, not affected by the flow direction of medium.
Working principle: the ventilation butterfly valve is driven by the motor to drive the actuator, so that the disc plate can rotate freely within 90 ° to achieve the purpose of opening and closing or regulating the medium flow.
