A butterfly valve has a turntable disc within a resilient, tubular seat member, the latter forming part of a conduit. The entire unit can be quickly disassembled for cleaning by detaching a segmented clamp which normally connects the tubular member with circular couplers at each side of the seat member. The couplers have grooves to receive raised ribs on each side of the tubular seat so that a tight seal can be formed. The clamp compresses the resilient tubular seat to insure a seal for the disc when the latter is turned to close the valve.
