Operating Principle
GDV160 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 drop. When on 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 valve to parallel passage, then, through spool opening to work port “A” or “B”.
As shown in above picture, the first spool is in neutral position, flow from pump flows to parallel passage through the load check valve to supply flow to two spool. Because the second spool is pulled out 7mm, the second spool opening between parallel passage to A2 port allows flow to enter the A2 port. B2 port connected to return passage. Neutral passage is blocked by second spool.
