Priority valve

OLS 320

High-flow priority valve OLS 320

High-flow priority valves are needed especially for
large tractors, wheel loaders, motor graders and
container trucks.

The new Danfoss priority valve OLS 320 can fulfill
demands from these applications.

The priority valve OLS 320 is to be used in connection
with Danfoss steering units type OSPC LS, OSPF LS,
OSPD LS, OSPQ LS and OSPL LS in load sensing
steering system with pump flow up to 320 l/min.

OLS 320 priority valve is available as in-line and
flange-on versions for EHPS.

Pressure drop P-EF is very low, less than 6 bar at 320
l/min at EF load higher than spring force.

Features

High flow capacity

•

Low pressure drop

•

Compact modular design

•

With or without built-in pilot pressure
relief valve
