Highlight: Lug type wafer butterfly valve
Product introduction:
Wafer butterfly valve is connected between two pipe flanges with a double bolt valve, its simple structure, small size, light weight, only by a few parts. And only need to rotate 90° can quickly open and close, simple operation, while the valve has good fluid control characteristics. When butterfly valve is in full open position, butterfly plate thickness is the only resistance when medium flows through the valve body, so the pressure drop produced by the valve is very small, so it has good flow control characteristics. Butterfly valve has two sealing types: spring seal and metal seal. Elastic seal valve, sealing ring can be mounted on the valve body or attached to the disc periphery.

Product features:
1. Design according with API 609/EN 593.
2. Tightness in both ways, lug type with threaded ears.
3. Flexible sleeve adapted to the shape of the body assures low operating torque. High and low semi stem giving a high flow coefficient, machined disc on periphery giving a low and regular torque.
4. Mounting flange according to ISO 5211.
5. Small operating torque, labor-saving dexterity, easy to operate,
6. Can be installed in any position, easy maintenance.
7. The sealing parts can be replaced, and the sealing performance is reliable, reaching the two-way sealing zero leakage.
8. Sealing material aging resistance, corrosion resistance, long service life.
9. Simple structure, good general interchangeability, high cost performance.
10. Stem seal is not easy to deformation, so as to avoid the common stem leakage phenomenon, the overall support is good, stable and reliable.
