Outline
This control valve consists of a 7-spool valve (the 6-spool valve + Hi valve) and 3 sets of Service valves. The merge/flow divider valve is installed to this.
All the valves are connected by a bolt to form one unit, and the passages are inter- nally connected, so the structure is compact and is very easy to Service.
This control valve is designed to assist only the boom and arm valves with their large flow using the Hi valve, so it has a simple structure.
