Danfoss PVG 32 Application Guide

Danfoss introduced the PVG 32 pressure control (PC) spools to the market in the 1990s to overcome
instability problems on applications and to control the opening of counterbalance (CB) valves. Typically, a
main boom on a crane could be applied with a CB valve for safety reasons. Inertia in the system could
lead to oscillations which will be damped when using PC spools.
In this document you can read about the hydraulic functionality and behavior of a PC spool compared to
our standard flow control (FC) spools. These hydraulic principles make it easier to know when to apply PC
spools instead of FC spools in different applications.
