Improved productivity and quality

We offer an incredible range of Vickers by Danfoss proportional directional valves with a variety of features, sizes, flow rates, and performance levels to meet customer demands in industrial and mobile markets.

With options for on-board electronics (OBE) and non-OBE, IP67 environmental protection, reduced power consumption, and more, Vickers valves reduce commissioning time, and long-term costs.

  • Size – NG 6 to NG 32 (D03 to D10)
  • Pressure – Up to 350 bar (5,000 psi)
  • Flow – Up to 700 L/min (185 gal/min)

Vickers by Danfoss proportional directional valves can help you:

  • Reduce commissioning time through plug-and-play functionality
  • Reduce labor time and costs through minimized wiring and easier service-ability
  • Increase automation and quality
  • Improve productivity and machine uptime

Upgrade to onboard (OBE) electronics

Proportional valves with onboard electronics offer several advantages, including a factory-matched valve and amplifier, which reduces the possibility of selection and installation errors. Installation and setup is faster and easier, with limited user adjustments and reduced electrical cabinet space requirements.

Our KB family of proportional directional valves with onboard electronics (OBE) features superior reliability and durability, IP67 environmental protection and reduced power consumption. With a controller built in, valves with onboard electronics (OBE) do not require an external controller.

Valves with OBE offer:

  • Easier setup with limited user adjustments for faster, lower cost valve package installation
  • Optimized valve with robust amplifier design
  • Reduced electrical cabinet space
  • Superior durability with high levels of EMC, vibration and shock resistance

Product range

Non-OBE proportional valves (without onboard electronics)

Three performance levels

Our proportional directional valves without OBE are available in three performance levels – ultra, high, and standard performance.

Design Proportional Valves without OBE

Ultra performance

KSD direct-acting and KHD pilot-operated servo performance valves.

  • Single solenoid high-response valve
  • Spool goes to 4th position when power is removed (pilot spool goes to 4th position on KHD)
  • Spool position feedback (pilot and main-stage spool position feedback)
  • Zero lap spool options
  • Suitable for closed-loop pressure and position control
  • Requires dedicated control amplifier
Design Proportional Valves without OBE

High performance

KFD direct-acting single feedback value.

  • Spool position feedback
  • Suitable for precise speed control and simple closed-loop applications
  • Requires dedicated control amplifier
Design Proportional Valves without OBE

Standard performance

KDG direct-acting and pilot-operated non-feedback valve.

  • No spool position feedback
  • Low-cost valve suitable for shock reduction and simple speed control applications
  • Simple, low-cost electronic requirements

OBE proportional valves (with onboard electronics)

Three performance levels

Our proportional directional valves with OBE are available in three performance levels – ultra, high, and standard performance.

  • Amplifier has spool position feedback (amplifier has only main-stage spool position feedback)
  • Zero lap spool options available on single-stage
  • Plug-and-play digital electronics with no amplifier-to-valve setup requirements, plus command options, enable function, and programmable ramps
OBE proportional valves

Standard performance

KBD direct-acting and pilot-operated non-feedback valves.

  • Dual solenoid digital valves
  • Spool stays in center position when power is removed (pilot spool stays in center position when power is removed)
  • No spool position feedback
  • Plug-and-play digital electronics with no amplifier-to-valve setup requirements, plus command options, enable function, and programmable ramps

Enhance your system with proportional valve electronics

Add precision, speed and accuracy to your industrial proportional valve application with Danfoss amplifiers and control cards. These add-ons feature user-friendly front panels with LEDs, so you can easily monitor and adjust card functions. The units provide both voltage and current input signals, with translation to standard, efficient PWM output signals.
