PVG 32 AG Modules Introduction The PVG 32 valve was originally launched with a range of high-performance electrical actuators in 1988. During recent years, several AG (agricultural) customer projects have motivated several innovations, and today our valve program offers components and features as compiled in this Technical Information or...
Technical Information PVG 32 AG Modules Function When main spools (15) are in neutral position, the pilot operated check valves (hereafter PO Check valves) are kept closed by a spring plus the work port load, which is directed to the spring side of the PO Check valves (14) via a small orifice.

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.
Technical Information PVG 32 AG Modules PVBD, PVBZ with optional diverter feature The utilization of a PVBZ module can be further enhanced by adding a diverter valve. Mounted on top of the PVBZ valve slice, a 6/2 PVBD diverter valve can direct valve flow to either of two set of ports (A1/B1 or A2/B2).
Work-modes are single-acting as it is standard today, but manual operation up and down are double-acting to increase comfort, functionality and safety. For further info and more details please see the Danfoss Hitch control System description, see Literature reference.

Technical Information PVG 32 AG Modules PVBZ-HS/HD, hitch control valves The flanged on multi-valve contains the shifting spool to switch port A between T and port A of the PVBZ. It also contains a PVLP shock/suction valve on port B.
PVG 32 valves with integrated HPCO functionality (High Pressure Carry Over). The HPCO function will guide the pump flow not used in the PVG 32 valve group via the HPCO port to for example a directional valve. The PVP pump side module with integrated HPCO function can only be mixed with PVB, PVBZ and PVST.
