Features:
1. The wafer butterfly valve is small and lightweight, easy to disassemble and repair, and can be installed in any position.
2. The stainless steel wafer butterfly valve has a simple and compact structure, small operating torque, and quick opening with 90° rotation.
3. The flow characteristics of the manual clamping butterfly valve tend to be linear and have good adjustment performance.
4. The connection between the butterfly plate and the valve stem adopts a pinless structure, which overcomes possible internal leakage points.
5. The outer circle of the butterfly plate adopts a spherical shape, which improves the sealing performance and extends the service life of the valve. It can open and close under pressure for more than 50,000 times and still maintain zero leakage.
6. The butterfly plate can be spray-coated according to user requirements, such as nylon or polytetrafluoroethylene.
7. The seals are replaceable and the sealing is reliable and bi-directional.
