Overview
Wafer Butterfly Valves are used to trim or control ambient or preheated air. The valve can be ordered with a hand lever or can be supplied with a lever and linkage for automatic control. When sizing wafer butterfly valves for automatic control, normal practice is to size for a valve differential pressure (∆p) of 10-20 % of total available air pressure. When ordering, specify temperature service desired: ambient air to 400 °F, or preheated air to 1200 °F.
