PVBZ basic module for EH auxiliary valve functions

PVG 32 AG Modules
The PVBZ valve is a load and pressure compensated valve module with two pilot operated check valves
(PO Check valves) in the A- and B-ports. These are limiting the work port leakage to a very low limit,
3
below 1 cm /min.
PVBZ modules will always have 2 PO Check valves one in each work port.
Besides compensation, the pressure compensator can limit the work port pressure blow up to 4 - 5 bar.
The special PVBZ load compensated module was developed for applications that require integrated pilot
operated check valves in the work ports that required to limit the port leakage to zero. See
The PVBZ basic module can be mixed with basic modules PVB (with additional tank line T0).
Features:
•
Integrated pilot operated check valves for limited internal leakage
•
Can be mixed with PVB with T0 gallery
•
LS a/b shuttle for float spools
•
Standard 4/4 float spools
•
Integrated thermo relief valve as option (modules with threaded ports only)
•
Manifold version for Danfoss designed valves or customer designed quick coupler block
•
Compensator with bleed off
•
Auxiliary valve on tractors for function control on implements; cylinder positioning and speed control
of hydraulic motors.
