Features

This product consists of a rubber-sealed butterfly valve with carbon steel or stainless steel disc and stem. Suitable for ≤120℃ applications in light textile, paper, food, pharmaceutical, chemical, petroleum, power sectors, etc., it regulates flow and intercepts media in water/gas pipelines.

1.Novel and reasonable design, unique structure, light weight, and quick opening/closing.

2.Small operating torque, convenient operation, labor-saving and dexterous.

3.Can be installed in any position for easy maintenance.

4.Sealing parts can be replaced, and the sealing performance is reliable to achieve bidirectional zero leakage.

5.Sealing materials are anti-aging, corrosion-resistant, and have a long service life.
