RS 160 is a sectional open center valve in a modular design that together with the wide range of standard parts offers maximum flexibility.

The valve is designed for high performance applications mainly in systems with fixed pumps but also for systems with variable pumps.

Two or more valves can be connected to each other in a range of different circuits.

The valve is very robust and well suited for demanding mobile applications. The sections are designed to meet the most stringent requirements on controllability.

General Information and Functional Description

General Information and Functional Description

 N/A The RS 160 is a proportional control valve according to the open-center principle with electro-hydraulic operation.

The maximum flow rate to the working ports A and B is 60 l/min. The spool 2.1 determines the flow rate and the flow direction.

The pressure control valves 2.3.1 and 2.3.2 are providing shifting pressure to the face sides of the main spool 2.1.

The level of electric current determines the level of pilot pressure and therefore the position of the spool.

Shock/anti-cavitation valves 2.5.1 and 2.5.2 protect the working ports A and B from pressure peaks and/or cavitation.

The check valve 2.2 in the parallel channel P" prevents the load from descending if the spool is moved and the pump does not provide the system with enough pressure (on A and B side).

Features

N/A

  • Flow-optimized valve design
  • Compact size and low weight
  • Several connection options for pump and tank
  • Applicable for constant and load-sensing pumps
  • Symmetrical sections (Inlet plate can be placed left or right)
  • Modular design up to 10 working sections
  • Operation type is electrohydraulic proportional (with/without hand lever)
  • Shock/anti-cavitation valves for protection of actuators
The modular system includes different types of inlets, sections and outlets. The valve is available with 1 - 10 working sections per valve assembly.

The sections are symmetric which makes it possible to use the valve both as "Left Hand Inlet" and "Right Hand Inlet".

Applications

Applications

 N/A RS 160 is designed as a flexible valve for a wide range of applications, but typical applications are cranes, wheel loaders and agriculture applications within the flow range for the valve.

Note

N/A The technical data were measured at a viscosity of 32 mm²/s.
Higher values are possible, depending on application.

  • 1 At 100 bar, 32 cSt and 40 ºC
  • 2 10 bar for internal connection Z → T
  • 3 Drained to tank preferred
  • 4 Higher viscosity allowed at start up
