Wafer Butterfly Valves for Hot Air WBV-H
Wafer butterfly valves designed to control high temperature ambient air or preheated combustion air.
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. Features and Benefits: • To trim or control ambient or preheated air • Available with hand lever or with lever and linkage for automatic control • WBV-H can be used in temperatures of up to 1200 °F for preheated air • WBV-H can be used in temperatures of up to 400 °F for ambient air
