Basic Operation Principle
GKV series sectional 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, then neutral passage is blocked. The flow from pump can only pass through parallel passage to load check valve, then, trough the bridge and spool opening to work port A or B.
For multi-section valves, if one of the section spool is in 1 or 2 position, then, there is no flow in its down stream section 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 section is dependent on the load.
