Pneumatic pressure regulation valve for a gas line has an additional pre-stop for the actuating membrane, or a component moved by it, as well as a final stop

摘要

Pneumatic pressure regulation valve (1), placed in a gas line, has a pressure regulation valve with an actuating membrane that is acted on on one side by a reference pressure and the other by the pressure that is to be regulated. The valve has at least a pre-stop (4) with which the membrane or a component moved by it comes into contact with and then as the membrane deforms further the valve opening is further closed, until in a final position it comes into contact with a final stop.
