Data Sheet
Priority Valve
Type OLSP
Introduction
Danfoss introduce a new priority valve for flanging on
gear pumps.
Use and function
The priority valve OLSP 80 is to be used in connection
with e.g. Danfoss gear pumps type SNP and steering
units type OSPC LS, OSPF LS, OSPD LS and OSPQ LS in
load sensing steering systems, where maximum oil
flow doesn’t exceed 80 l/min.
OLSP priority valves are to be flanged on gear pumps
with outlet ports square flange type 35.
Versions
Load sensing static priority valves
Load sensing static steering units require load sensing
static priority valves. Load sensing static steering
systems have no oil flow in the LS connection when
the steering unit is in neutral position.
Load sensing dynamic priority valves
Load sensing dynamic steering units require load
sensing dynamic priority valves. Load sensing
dynamic steering systems have a constant oil flow in
the LS connection from the priority valve to the
steering unit even when the steering unit is in neutral
position.
