Abstract

In a method of sealing a valve of the kind comprising a closure member 1 movable into engagement with a seat 6, the closure member 1 having an element 5 with a sealing surface inclined relative to the direction of movement of the closure member 1, at least the sealing surface of the closure member 1 is made of a material that is so much harder than the material of the valve seat 6 that the normal closing power of the valve is able to create plastic deformation of the valve seat 6 by means of the closure member 1. As a result, the valve seat 6 is deformed in accordance with the form of the sealing surface of the closure member 1. <IMAGE>
