Flanged Butterfly Valve

Product Introduction

Yifa double flanged butterfly valve is an industrial valve that controls the flow of pipeline media through the rotation of a disc. It is primarily used in water supply and drainage, metallurgy, energy systems, and textile industries, with temperatures ≤120-150°C and nominal pressures ≤1.6 MPa. The valve stem center is located at the intersection of the valve body centerline and the disc sealing section. The valve seat, a composite design of synthetic rubber and polytetrafluoroethylene, achieves a seal through elastic deformation, offering both wear and corrosion resistance.

This valve features a compact structure, low operating torque, and quick 90° opening and closing. It supports manual, electric, or pneumatic actuation.
