• 5 pressure adjustment stages - permits an accurate adaption to the application
• Short delivery time for most variations - no warehousing necessary
• Max. pressure settings of:
    - 25, 64, 160, 210, 350 bar for RDM2,
    - 19, 50, 100, 150, 210 bar for RDM3.
• Adjustment modes:
    - Slotted head with lock nut
    - Cylinder lock
    - Turning knob
• Gauge port
• RDM2 - NG06 (CETOP 03), RDM3 - NG10 (CETOP 05)

Applications:
• Suitable for general hydraulic applications

Function:
Code PT: pressure is relieved from P to T at the adjusted value
Code TT: pressure pre-loading in T
