Doosan DL220BLOCK VALVE Theory of Operation

 

This article mainly introduces Doosan DL220BLOCK VALVE Theory of Operation

 Doosan Diagnostic Tool DDT

 The block valve is made up of four bypass check valve C1.

Output from the steering pump passes through the priority valve that is part of the steering cylinder. See the hydraulic schematic.
(Figure 84). This flow then passes out of the steering cylinder and enters the block valve at port EF. This allows output from the steering pump to join flow from the main pump to supply the boom, bucket, and option control valves.
