1. Things to Know About China
Butterfly Valve

2. The butterfly valve in China is a quarter-turn valve used for controlling
flow. Its disc moves like a fluttering butterfly, opening or closing when
the rod is rotated 90 degrees. It is known for being quick, cheap, and
lightweight, with manual or automatic operation depending on size.
Lining separates the valve body from the media, reducing costs and
materials.

Main Parts of a Butterfly Valve?

4. Butterfly valves are quick and easy to open and control media flow.
They consist of a body, seat, disc, and stem. The disc seals the flow
when closed and can partially open for flow regulation. The valve can
be operated manually, pneumatically, or electronically. Opening
requires a quarter turn, allowing full flow, while closing requires
another quarter turn for full closure. Throttling adjusts flow by varying
the disc angle. Installation is typically done in the open position to
avoid seat wedging.
