Abstract (en)
[origin: EP1010898A2] The way valve (10, fig.1) works in conjunction with a changeover valve (30, fig.1). The pressure medium connections between at least two pilot ducts (32,34) and a control duct (38) leading to the pilot control unit (22, fig.1) connect with the help of a closing unit (30, fig.1). The closing unit (36) connects automatically and independently from its mounted position and the type of the pressure medium supply of the pilot duct (32,34) conducting the control pressure, connects with the control duct (38) and simultaneously closes the pilot duct (32,34), not needed for the control pressure control.
