Abstract
A valve controlled in dependence on differential pressure comprises a valve housing (4), a diaphragm housing (16) fastened thereto, and connected therewith a setting device (3) with a set-point spring (50). Fastened in the centre of the diaphragm (23) there is an insert (26) against which an end contact face (28) of the valve rod (7) lies. The insert (26) is connected by way of an articulation (37) to a pin (36) which projects into the setting device (3) and is there loaded by the set-point spring (50). In that manner, the valve movement is prevented from being obstructed by the influence of transverse forces.
