Overview

SENSI Concentric rubber lined butterfly valve is suitable for food, medicine, chemical, petroleum and electric power with temperature ≤120°C and nominal pressure ≤16MPa; Metallurgy, urban construction, textile, papermaking and other water supply and drainage, gas pipelines for regulating flow and intercepting medium


Characteristics

1. The design is novel, reasonable, unique in structure, light in weight, and quick to open and close.

2. The operating torque is small, the operation is convenient, and the labor is dexterous.

3. It can be installed and maintained in any position.

4. The seal can be replaced and the sealing performance is reliable to achieve zero leakage in the two-way seal.

5. The sealing material is resistant to aging, corrosion and long service life.
