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
•Optional port connections
•Available for both static and dynamic systems
