  • Page 5: Introduction

    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...

  • Page 6: Function

    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.
