Danfoss spools for the PVB sections of the PVG 32, from 10 to 130 l/min: closed or open centre, with LS a/b, for hydraulic actuation and for friction detent.
Danfoss spools for the PVB sections of PVG 32 proportional directional valves. The spool sets the maximum flow of each port and how the section behaves in the neutral position.
Versions of 10, 25, 40, 65, 100 and 130 l/min are available, in several types:
standard (157B7000 to 157B7006) and open centre (157B7100 to 157B7106);
with LS a/b, for sections with LSA/B valves (157B7020 to 157B7024);
for load holding valves (157B7011 to 157B7013);
for PVH hydraulic actuation (157B9000 series);
for PVMR friction detent control (157B9700 series), closed centre, open centre or with LS a/b;
special PVBS and PVSK spools, identified by code.
To choose, use the code of the old spool or the valve's parts list. Check the flow, the centre type and the section's actuation.
