Abstract
Abstract A dismountable valve assembly having a valve body made up of separately prefabricated tubular portions, a spacer plate containing a valve seat situated between each pair of adjacent tubular portions, cover elements covering either end of the valve, fastening bolts releasably fastening the tubular portions, their associated spacer plates and the cover elements, and a valve stem, carrying a valve disc. The valve stem extends through one of the adjacent tubular portions and is movably mounted so that its valve disc may alternately engage and disengage the valve seat of the spacer plate with which it is associated.
