Abstract (en)
[origin: EP0080441A2] A valve device for controlled pressurization of a pressure fluid system (35). The device comprises two coaxial valve bodies (9, 13), one (11) for controlling flow communication between inlet port (5) and outlet port (6) and the other (9) for controlling flow communication between outlet port (6) and drain port (7). The coaxial build-up gives short and direct channels and thus small dimensions for a given flow capacity.
