ABSTRACT:
The invention is directed to a valve wherein the valve closure body includes two bracing elements lying in contact engagement with the inner wall surface of the wall casing of a conduit. The two bracing elements are disposed in spaced relationship to each other so that this spacing defines a squeeze zone at which a squeezing pressure can be applied. The squeeze zone has a length which corresponds approximately to the wall spacing within the sleeve. When the elastic wall casing of the conduit is squeezed in the squeeze zone, a portion of the casing deflects to allow passage of a fluid through the conduit.
