POL, PRL, PIL - Proportional directional spool valves

Product description

The directional spool valve type POL, PRL and PIL is a 4/2- or 4/3-way directional spool valve with standard connection pattern NG 6(CETOP 3) and NG 10(CETOP 5). It is directly actuated and proportionally activated.

The directional spool valve is available for manifold mounting. Areas of application include industrial hydraulics, particularly machine tools.The valve is particularly suitable for press brakes with closed-loop control via an external amplifier (e.g. EV2D) when high resolution with low hysteresis is required.

Features and advantages

  • High flexibility by means of a variety of circuit symbols
  • Directly and proportionally controlled
  • Good resolution
  • Low hysteresis through integrated displacement transducer
  • Directly actuated proportional directional spool valve with integrated displacement transducer
  • High resolution for precise and sensitive control
  • Low hysteresis due to continuous feedback of the spool position
  • Analog position output (LVDT) and digital centre-position signal

Intended applications

  • Hydraulic power packs
  • Industrial hydraulics
  • Press brakes
