Danfoss PVE Series 7 Actuators



Danfoss PVE Series 7 Actuators

The PVE series 7 is the newest actuator series to join the successful Danfoss PVE portfolio, which offers customers fast, accurate and intelligent operation with plug-and-perform design and works in conjunction with Danfoss high performance proportional valves — PVG 32, PVG 100, PVG 120 and the new PVG 128 and PVG 256, as well as steering valves EHPS, EH, EHi and OSPE.

High Precision

Standard for all proportional PVE S7 is the use of a spool position feedback signal to close the loop on the PVG/steering valve main spool position, ensuring it is in the right position at a given input signal. This ensures high precision of the valve flow with high repeatability which leads to improved machine performance and productivity as well as less operator fatigue. 

Improved reliability and safety

Danfoss PVE Series 7 actuators come with built-in safeguards, including fault monitoring and options of spool direction indication, spool position feedback and separate float control. The enhanced spool position sensor with dual demodulator increases the diagnostic coverage to make the actuators safer and more reliable. “With this advanced diagnostics system, we are checking that the spool position signal is not corrupted, ensuring high reliability,” added Knud Meldgaard Jensen. 

Individual benefits

The new PVE Series 7 has a number of proven-in-use features that deliver the high reliability expected of a Danfoss Power Solutions product. 

  • Ability to easily upgrade to the new PVE Series 7 actuator from PVE Series 4, as it is 100 percent backward compatible with PVE Series 4 actuators. The PVE Series 7 will seamlessly replace PVE Series 4 actuators, while providing customers with all the new benefits.
  • More space available around the valve due to the compact design of the new PVE Series 7, providing the OEMs with a better design flexibility.
  • A microcontroller designed with embedded software algorithms, which gives increased repeatability and superior performance.
  • Improved robustness and environmental withstand. An increased temperature range from -40 to +90 °C, allows the PVE Series 7 to operate in extreme conditions anywhere in the world, which results in more competitive machines for the OEMs.
  • Easy to install on the machines and to be tested. Easy system upstart and event monitoring enabled by LED lights on all actuators so the electronic wiring can be tested without powering up the hydraulic system.
  • Save time and extra expenses related to machine EMC testing when upgrading from PVE Series 4 to PVE Series 7 as the PVE Series 7 is E-marked according to UNECE R10.
