Sectional directional control valves

Sectional directional control valves

HYDAC’s open centre directional control valves work primarily with fixed displacement pumps.

Valves include:

Directional control valves RS160, RS220, RSQ240 and DX-6 are also compatible with variable displacement pumps.

Types of actuation range from hand lever, Bowden cable, hydraulic, pneumatic, electrohydraulic or electronic control units.

Position monitoring sensors are also available.

Furthermore, there are optimised main control pistons for different applications.

The directional control valves are developed with a focus on high precision, fine control, and energy efficiency.

Due to flexible structure and compact design, the valves are suitable for many applications.

 

Open-centre sectional directional control valve RS160

The RS160 is a proportional control valve according to the open-centre principle with electro-hydraulic operation.

Open-centre sectional directional control valve RS160 product features

Open-centre sectional directional control valve RS160 product features include flow-optimised 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, electrohydraulic proportional operation type (with/without hand lever), and shock/anti-cavitation valves for protection of actuators.

 

RS160 technical data

Open-centre sectional directional control valve RS160 technical data is as follows:

  • maximum pressure: 250 bar
  • maximum flow rate: pump port - 60l/min, working ports - 60l/min

 

Sectional directional control valve RS 210

Key valve features

The RS 210 is a sectional open centre valve designed for maximum operating pressures up to 300 bar and maximum pump flows up to 70l/min.

RS 210 is available with one to 10 working sections per valve assembly.

The valve can be used in different systems for parallel as well as tandem circuits.

It is designed with an open centre for fixed and variable displacement pumps.

The valve can be operated manually, with cable or by pneumatic and electropneumatic or electro-hydraulic remote control.

RS 210 offers excellent operating characteristics because of specially designed spools for different applications. Low and uniform spool forces are the result of careful balancing of flow forces.

 

Technical data

Sectional directional control valve RS 210 technical data is as follows:

  • maximum operating pressure per port:

P1, P2, P3, P4 - 300 bar

T1, T2, T3, T4 - 20 bar

  • maximum permissible flow either on port:

P1, P2 inlets type A, B, C, E - 50l/min

P1, P4 inlets type Q - 70l/min
