Abstract

The valve comprises a body containing a closing member with a sealing surface at the intersection of an inlet duct and an outlet duct for the passage of gas, a piston subjected to the action of a spring or the like and a control device being connected to the closing member via a pusher and via a sealing diaphragm arranged between the pusher and the piston. To lengthen the service life of the diaphragm, the diaphragm is associated with a washer comprised of a slightly deformable material.
