Butterfly valves are a family of quarter-turn rotational motion valves that are used in pipelines to shut-off flow. It is often said that butterfly valves can be used to regulate the flow. However, we do not recommend doing this, as it can damage the valve disk and have a negative effect on the sealing properties.
FLANGE TYPE BUTTERFLY VALVE:
Flanged butterfly valve is a type of valve that is commonly used in industrial processes to control the flow of fluids.
Flanged butterfly valves are designed to be bolted to the flanges at each end of the valve. They have a raised surface on each flange to provide a surface for the gasket.
WAFER TYPE BUTTERFLY VALVE:
The valve is designed to clamp between two flanges in your pipe work. Most wafer butterfly valves fit the majority of flange standards. The rubber or EPDM valve seat creates an exceptionally strong seal between the valve and flange connection.
