Abstract
Dual-circuit pressure control valves are known in which the two control pistons are acted upon by a common preloading force through the intermediary of a preload distributor. The disadvantage of the known devices is that the valve closure travel is great resulting in a large fluid volume input to the control valve. According to the present invention this disadvantage is overcome by providing adjustable stops which cooperate with corresponding extensions of the distributor as soon as an unsymmetrical mode of operation of the valves occurs.
