HYDRAULIC SECTIONAL CONTROL VALVE WITH MULTIPLE RELIEF SLOTS |
| 摘要 |
A working valve section for a sectional fluid control valve comprising a valve section housing having a substantially planar surface for being attached to an adjacent valve section housing; a main control spool bore (43) extending into the housing substantially parallel to the planar surface; a compensator spool bore (46) extending into the housing substantially parallel to the planar surface, the compensator spool bore being spaced from the main control spool bore; a first relief slot (49a) extending across the planar surface substantially coextensive with the main control spool bore; and a second relief slot (49b) extending across the planar surface substantially coextensive with the compensator spool bore. |

1. A working valve section for a sectional fluid control valve comprising:
a valve section housing having a substantially planar surface for being attached to an adjacent valve section housing; a main control spool bore extending into the housing substantially parallel to the planar surface; a compensator spool bore extending into the housing substantially parallel to the planar surface, the compensator spool bore being spaced from the main control spool bore; a first relief slot extending across the planar surface substantially coextensive with the main control spool bore; and a second relief slot extending across the planar surface substantially coextensive with the compensator spool bore. |
