Danfoss’ New High-Flow Proportional Valves

Designed for applications such as large mobile/truck mounted cranes, crawler cranes, ship cranes, winches or drilling machines, Danfoss Power Solutions has added two high-flow proportional valves to its PVG portfolio.

The addition of the new model PVG 128 and PVG 256 valves are also designed to 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.

Knud Meldgaard Jensen, global product marketing manager for Danfoss Power Solutions said that the company’s off-highway OEM customers can use the PVG 128 and PVG 256 valves to achieve the high flow necessary for their applications but can combine them with the PVG 32 and PVG 16 for lower flow functions in their machines as well.

“By keeping the same design concept as the PVG 32 and PVG 16 valves, our customers can easily add and combine the PVG 128 and 256 valves into their custom design,” Meldgaard said. “The valve modularity ensures OEMs can easily optimize their machine using the entire PVG valve range — saving on space, weight and costs.”

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