Butterfly valves for gas are a type of shut-off valves designed to control the flow of gas in pipeline systems. Their design includes a disk that rotates around its axis to regulate or completely block the flow of the working media. The name “butterfly” is associated with the shape of the device body, reminiscent of butterfly wings.
Advantages of butterfly valves for gas
- High tightness due to the use of NBR seals.
- Easy installation due to wafer connection.
- Compact dimensions and light weight reduce the load on the pipeline system.
- Possibility of precise regulation of gas flow.
Safety in Use
Working with natural gas requires special attention to safety due to its explosive properties (methane concentrations of 5% to 15% in air can cause an explosion)
