| Describe |
| Type DR pressure valves are pilot operated pressure reducing valves, which are controlled from the secondary circuit. They basically consist of main valve with main spool insert and pilot control valve with pressure adjustment element. |
| At rest, the valves are open, this means that fl uid can freely pass from port B, to port A via the main spool insert. Pressure present in port A acts on the under side of the main spool. At the same time there is pressure acting on the ball in the pilot control valve via the orifi ce on the springloaded side of the main spool and via port. This pressure also acts on the ball, via the orifi ce, control line, check valve and orifi ce. |
