Abstract

A three-way or multi-way valve (1) is provided, which is built up of a plurality of two-way valves (11-14), each of which has a high pressure connection and a low pressure connection which are separated from each other by means of a valve seat with which a closure element co-operates, the two-way valves (11-14) being arranged to be operated in pairs or in groups by means of a control pressure fluid by way of a control pressure line (40a, 40b) opening into a pressure chamber (35a, 35b, 36a, 36b), and one of the two-way valves (pump valve 11, 12) of each group being arranged in a connection between a pressure source (6) and a load (2), and another two-way valve (tank valve 13, 14) of the same groups being arranged in a connection between the load (2) and a pressure sink (7). A valve of this type should also be able to be operated reliably when water is used as hydraulic fluid. For this purpose, there is arranged in the control pressure line (40a, 40b) at the tank valve (13, 14) a non-return valve (37a, 37b) which closes towards the tank valve.
