Technical Information
PVSK module with integrated diverter valve and P-disconnect function
Introduction
Danfoss introduces PVSK-modules with integrated diverter valve and P-disconnect function.
The module is intended for cranes, telescope lifts and other applications that have special demands on functionality and safety.
The PVSK-module can be integrated in PVG 32 valve groups for openas well as closed-center systems.

PVSK spool |
Functions of the PVSK-module:
•When the diverter valve is in neutral position, there is no pressure (only tank pressure) in the P- channel of the valve group.
•When the diverter valve spool is actuated in A-direction, it enables the basic modules in the PVGgroup to receive pump flow supply.
•When the diverter valve spool is actuated in B-direction, it enables the (High Pressure Carry Over) HPCO-port in the PVSK module and the P-cannel in the valve group to receive pump flow supply.
