Hydraulic system distribution box - has shut-off valve in second circuit opened by pressure in first circuit

摘要

The box has an upstream inlet for the fluid under pressure and two downstream outlets for separate systems served. Inside it are two circuits emanating from the inlet and leading to the different outlets, the first circuit incorporating a non-return valve. The second circuit has a shut-off valve subject to the pressure in the first one downstream of the non-return valve. This valve is opened when pressure in the first circuit reaches a predetermined value. The non-return valve can be of the spring-loaded ball type. The design ensures that two functions are performed one after the other.
