The clamp type manual butterfly valve is composed of a rubber sealed butterfly valve, a carbon steel or stainless steel valve plate, and a valve stem. Suitable for regulating flow and intercepting media on water supply and gas pipelines with temperatures ≤ 80-120 ℃, such as food, medicine, chemical, petroleum, electricity, light textile, papermaking, etc. Its main characteristics are:
1. The design is novel, reasonable, and structurally novel, with light weight and quick opening and closing.
2. Small operating torque, convenient operation, labor-saving and agile.
3. Can be installed in any position, convenient for maintenance.
4. The sealing element can be replaced, and the sealing performance is reliable, achieving zero leakage in both directions.
5. The sealing material has characteristics such as aging resistance, weak corrosion resistance, and long service life.
