Butterfly Valve: Butterfly Valve has a similar operation like Ball Valve. It is used to block the flow of Media (like Water, Chemical etc.). Generally, user preferred butterfly valve instead of ball valve because it is economical. It is available in Minimum size of 40mm. Butterfly valve has a simple structure which is contain Body, Seal, Stem, Rubber seat (Nitrile, EPDM, Viton), Disc (Sg Iron, SS) & Lever. It is easy to use by Lever & Gear. It will also operate by Actuator. Basically, up to 150mm butterfly valve is operated by Hand Lever & Above 150mm butterfly valve is Gear Operated.
There is various type of Butterfly Valves Like: –
According to Flow of circuit
- Wafer Type Butterfly Valve
- Semi Lug Type Butterfly valve.
- Lug Type Butterfly valve.
- Double Flanged Type Butterfly valve.
- Motorized Butterfly valve.
Butterfly valve is also known as quarter-turn valves in the family of Valves. Butterfly valve has a different type of pressure rating & Different usage which depends on MOC of rubber & Disc. Butterfly valve available in SG Iron (Cast Iron), Cast Steel, SS304, SS316, Aluminum body.
