Corrosion-resistant butterfly valve adopts special high temperature moulded fluorine (glue) lining technology, the inner cavity flow machine parts (valve body and valve plate, etc.) are processed by lining, and all have passed 25000V high pressure electric spark micro-gap detection.

Through the combination of materials, it can be used to control the pipeline of highly corrosive medium, such as any concentration of strong acid strong alkali and high oxidation chemical solution. It has the following characteristics:

1. The lining layer is reliable and has been detected by high voltage edm gap;

2. High strength silicone collective gasket, reliable sealing without leakage;

3. Easy installation, 90° opening and closing, quick cutting off and adjusting flow, light operation.
