Abstract

PURPOSE:To obtain a butterfly valve having a low manufacturing cost, a light weight and a sufficient strength by forming a valve housing barrel from a steel pipe material with the use of a bulge process, and by inserting a cartridge type valve seat replaceably in the valve housing barrel. CONSTITUTION:An annular valve housing barrel section 1f, a valve housing lower neck section 1b, a valve housing upper neck section 1d are formed from a steel pipe material with the use of a bulge process, and a manipulator holding section 1c is welded to the valve housing upper neck section 1d so as to constitute a valve housing 1. A cartridge type valve seat 2 composed of a resilient member 2a and an annular reinforcing member 2b is replaceably inserted in the valve housing barrel section 1f. A valve element 5 having a valve rod 4 is disposed in the valve seat 2. With this arrangement, it is possible to manufacture the valve housing at a low cost while it is possible to compensate the valve housing having a thin wall thickness for its insufficient strength by use of the cartridge type valve seat 2.
