A butterfly valve has a housing formed from two stamped sheet parts. The shaft of the valve flap is located in shaped-out parts of the housing halves. The two flanges of the housing halves are held together by a clamp, which has an inwardly open, U or V-shaped cross-section and can be secured in articulated manner by two semicircular parts and presses by chamfered inner faces on tori on the flanges. Thus, the valve can be assembled and disassembled by loosening a single screw.


A butterfly valve comprising: a housing, a flow channel passing through the housing and a disk-shaped valve flap swivelable by a rotatably mounted shaft closing the flow channel, the housing having openings for rotatably mounting the shaft, the housing being subdivided into two parts along a separation plane at right angles to the flow channel, the two parts having in each case an outwardly projecting flange, the flange having a surface directed towards the separation plane and an outer surface directed away from the separation plane, recesses being prov...
