Operating Principle
GDV70 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”.
As shown in above picture, when first spool is in neutral, flow from pump passes through load check valve and center the parallel passage to supply flow to both spool. Due to second spool is moved to “2” position, the flow from parallel passage flows to “A2” through the spool opening. The flow from “B2” flows to return passage through the spool’s another opening. Neutral passage is blocked by the second spool.
