High-Flow Valves for Demanding Applications


The PVG portfolio has expanded to include the PVG 128 and PVG 256 valves that are designed to easily integrate with the existing line of Danfoss high performance proportional valves — PVG 16 and PVG 32 — allowing modularity from low to high hydraulic flow within the same valve stack. 


These high-flow valves are ideal for use on demanding applications such as large mobile/truck mounted cranes, crawler cranes, ship cranes, winches, drilling machines, etc. where flow and durability is essential. Using the PVG 128 and PVG 256 together with other valves in the PVG family allows OEMs to easily enhance machine performance while improving productivity and lowering energy consumption. 





The addition of the high-flow valves extends the range of hydraulic flow within the PVG series up to 300 liters (79 gallons) per minute with the PVG 128 and up to 400 liters (105 gallons) per minute with the PVG 256. A special turbo version of the PVG 256 valve is also available, increasing the hydraulic flow up to 500 liters (132 gallons) per minute. 


Modular valve concept
The high-flow valves are designed to work in conjunction with the smaller valves in the PVG portfolio, delivering consistent performance throughout the entire valve range. A total of four different valve sizes offer OEM customers more options — all of which utilize the same electrical and hydraulic interfaces to fit the exact flow needed for each application. The use of common parts within the PVG platform means the high-flow valves can easily be incorporated into existing applications.


Flexible spool options 
Danfoss PVG valves offer multiple spool sizes that can be adapted to meet customers’ specific application needs. Available spools are a combination of linear and progressive, meaning the same spool can be used for all configurations with and without LS A/B relief valves. 



  • High performance and productivity The PVG 128/256 valves are a pre-compensated valve, and provide the reliability necessary for the most demanding applications.
  • Reduced costs and installation complexity The PVG 128/256 valves can easily adapt to regional fitting standards.
  • Optimal productivity and precise operation — The valves offer smooth, load-independent flow control.
  • Improved energy efficiency and safety — Individual load-sensing A/B relief valves limit the pressure on each work port of a valve section, reducing material stress.
  • A consistent control interface and easy setup — The PVG 128/256 uses the same actuation type as the PVG 32 and PVG 16 valves, meaning it’s already compliant with electrohydraulic actuators, PVHC actuators and PLUS+1.
  • Optimized operator productivity — Using the PVE S7 and PVED S5 from Danfoss in conjunction with the PVG 128/256 valve ensures a high degree of precision and repeatability of the valve performance.
  • Additional diagnostics — CANbus control lowers the cost of installation and ensures data availability on the machine’s existing bus system.
  • Reliable operation — Each valve section has a manual control that allows work to continue even in the event of electrical power failure.
