Four way pressure balanced valve - has balance control pressure arranged to regulate valve and hydraulic control valve

摘要

The four way valve is combined with a two way pressure balance. For both directions of movement of the consumer, one control pressure for the pressure balance is taken off one consumer connection of the path valve. When the pressure balance is arranged in the outlet, either the pump pressure or the control pressure of the balance, forms the other control pressure. When the pressure balance is positioned in the inlet, the second control pressure is formed by the tank pressure of by the regulating pressure of the balance. The control pressure for the flow balance for both movement directions of the consumer is taken off the consumer connection of the path valve, and simultaneously forms the control pressure for a hydraulic control valve.
