PVBS Main Spools

62 | © Danfoss | December 2018
The main spools (PVBS) determine the flow out of the work section or the pressure build up and are
based on a generic platform with a wide selection of additional features, enabling you to tailor the PVBS
to suit the demands of any hydraulic system and any function.
The PVBS main spool can be activated in three different ways:
•
Mechanically by a PVM lever
•
Electrically by a PVE/PVHC actuator
•
Hydraulically by a PVH actuator
