Grooved clamp type butterfly valve

Nominal pressure:PN1.0~2.5MPa
Nominal diameter:DN50~300mm

This product is a new type of valve developed by our company, which has the advantages of quick installation, simple and reliable, light weight, flexible operation and easy maintenance. In particular, it has both the good sealing characteristic of eccentric butterfly valves and the fast connection required by pipe fittings. It can be widely used in water supply and drainage, fire, petroleum, chemical, medicine, steel, etc., using the new domestic trench pipe fitting pipe as a cut-off or adjustment.

1. The clamp butterfly valve seal is designed with foreign new technology to become an eccentric sealing pair after compression and less movement, light degree of friction (basic. No friction on), so less wear, durable;

2, the butterfly plate adopts the European first-class rubber vulcanization technology, so that the whole butterfly plate is coated with rubber, which can ensure the precise geometric size of the butterfly plate, interchangeable, strong, corrosion resistance;

3. The inside and outside of the valve body are coated with powder epoxy resin, which can prevent the corrosion of the valve body and avoid the phenomenon of hot metal in the valve;

4, the valve stem and valve body with three "O" ring sealing ring seal design, greatly reduce the friction resistance when switching, greatly reduce the water leakage, so that the valve is often switched without leakage;

5, clamp type butterfly valve compact structure, small size, light weight, flexible operation, easy maintenance;

6, the design adopts eccentric bidirectional sealing principle, reliable sealing performance, is not limited by the flow direction of the medium;

7, the flow area is large, the flow resistance coefficient is small, the flow capacity is large;

8, anti-aging, anti-radiation, durable.
