Operating Principle
GDV80 series mono-block valve is an open centered, 3 position 4 way valve. When spool is in its neutral position, the flow from pump passes through the neutral passage to tank, with very low pressure drop. When one of the spool is moved to “1” or “2” position, the neutral passage is blocked. The flow from pump can only pass through load check to parallel passage, then, through the spool opening to work port “A” or “B”.
For multi-spool mono-block valve, if one of the spools is in “1” or “2” position,then, there is no flow in its down stream spool’s neutral passage. The main throttle occurs on the valve opening between bridge passage and spool. The operator can control more than one spools, but the magnitude of the flow rate for each controlled spool is dependent on the load.
