Danfoss Power Solutions has added two high-flow proportional valves to its PVG portfolio, the PVG 128 and PVG 256 valves.
- Designed to easily integrate with 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
- High-flow valves
- Well suited for use in demanding applications such as large mobile/truck mounted cranes, crawler cranes, ship cranes, winches, drilling machines, etc. where flow and durability is essential
- Using with other valves in PVG family allows OEMs to easily enhance machine performance while improving productivity and lowering energy consumption
- Extends range of hydraulic flow within series up to 300 lpm (79 gpm) with the PVG 128 and up to 400 lpm (105 gpm) with the PVG 256
- Special turbo version of PVG 256 valve is also available, increasing hydraulic flow up to 500 lpm (132 gpm)
- Use of common parts within PVG platform means the high-flow valves can easily be incorporated into existing applications
- Pre-compensated valves
- Offers smooth, load-independent flow control
- Individual load-sensing A/B relief valves limit pressure on each work port of a valve section, reducing material stress
- Uses same actuation type as PVG 32 and PVG 16 valves, assuring compliance with electrohydraulic actuators, PVHC actuators and PLUS+1
- Use of PVE S7 and PVED S5 from Danfoss in conjunction with PVG 128/256 valves ensures high degree of precision and repeatability of valve performance
- CANbus control lowers cost of installation and ensures data availability on machine’s existing bus system
- Each valve section has manual control that allows work to continue even in the event of electrical power failure
