Butterfly valves for gas Description
Gas Butterfly Valve is a valve specially used in gas pipeline systems. It controls the on-off or flow regulation of gas by rotating the butterfly plate. Its core structure includes the following components:
Valve body: the main frame, mostly cylindrical in design, used to connect the pipeline.
Butterfly plate (valve flap): a disc-shaped component that can fully open or close the flow channel when rotated.
Valve stem: connects the operating mechanism and the butterfly plate to transmit the rotational power.
Sealing ring: usually made of soft materials (such as rubber) or composite materials (such as stainless steel + T-shaped sealing ring) to ensure sealing.
Operating mechanism: manual, pneumatic or worm gear drive device, used to control the rotation angle of the butterfly plate.

Advantages and Disadvantages of Gas Butterfly Valve
Advantages:
Quick opening and closing, low fluid resistance.
Easy maintenance, long service life.
Applicable to medium containing particles (such as impurities in gas).
Disadvantages:
Poor sealing performance under high pressure/high temperature conditions.
Not suitable for high-precision flow control.
The butterfly plate and sealing ring are prone to wear after long-term use.
