Butterfly Valves



Butterfly Valves

When Using larger Throttling Valve, using flanged piping connections, BUTTERFLY VALVE should be considered.
Generally BUTTERFLY Valves are low pressure valve with a simple 90 disc stem operation. In some cases, they are used as shut off valves although offering pressure drop through the valve opening.

The usefulness of the BUTTERFLY VALVES has increased with the development of elastomer liners with a wafer body which provide a tight shut-off. Such liners normally utilize back-up rings in the body to effectively support the liner. This provides sealing of the liner against the disc as well as the adjacent flanges.
