PRE- AND POST - COMPENSATIONAL VALVE ARRANGEMENT |
摘要 |
Hydraulic valve arrangements may be assembled to provide pre-compensation or post-compensation using the same chassis body. A first type of main spool is disposed in a main passage and a first type of pressure compensator spool is disposed in a compensator passage to provide pressure pre-compensation. The first type of pressure compensator spool connects to a first pilot location and not to a second pilot location. A second type of main spool is disposed in the main passage and a second type of pressure compensator spool is disposed in the compensator passage to provide pressure post-compensation. The second type of pressure compensator spool connects to the second pilot location and not to the first pilot location. The valve arrangement may be switched from pre-compensation to post-compensation (or vice versa) by switching out the main spool and pressure compensator spool without making any other changes to the chassis body. |
