Tilting Disc Valve

The tilting disc valve accomplishes full flow opening by having the disc pivot or “tilt” in the flow of the media, which causes the TD series to have an incredibly low opening stroke range. This reduces the opening and closing times critical to controlling flow reversal and reducing water hammer. Available in both top and bottom mount configurations.
