Abstract
A valve assembly for an apparatus under pressure, includes a valve casing with a connecting pipe having formed therein a fluid passageway. A valve body is received in the valve casing and movable against a valve seat for sealing the fluid passageway and thereby separate a high-pressure zone from a low-pressure zone. Integrated in a handwheel of the valve body is a manometer which is constraint against rotation, when the handwheel is turned with respect to the manometer. The manometer is in communication with the high-pressure zone regardless whether the valve seat is closed or open.
