Lever Operated Wafer Butterfly Valve , Cast Iron Concentric Butterfly Valve

A butterfly valve is a regulating and shut-off device that can be an alternative, in some applications, with globe and ball valves.

This type of valve may be classified base on multiple parameters:

• design: centric, double eccentric, triple eccentric
• end connection type: wafer, lug (semi or full), flanged and double flanged
• seat material: soft (example: , Buna, rubber, etc) or metal-to-metal (SS304, SS316)
• body and disc materials (from cast iron to high nickel alloys)
• actuation: manual (lever, gear, a worm gear) and actuated (electric, pneumatic, hydraulic and gas-over-oil types)
