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.

Features

•For flanging on pumps directly

•Simplified installation

•Compact design

•Low pressure drop

•Optional port connections

•Available for both static and dynamic systems
