Danfoss Introduces New PVG High-Flow Proportional Valves with Pre-Compensated Valve Design
Press Release Summary:
PVG High-Flow Proportional Valves now include PVG 128 and PVG 256 valves with hydraulic flow of up to 300 L and 400 L per minute respectively. The valves come with control interfaces such as mechanical (PVM), hydraulic (PVH), high current (PVHC) as well as CANbus control (PVED S5). These valves are adaptable to regional fitting standards and are offered with variations to SAE- and Metric flanges. Unit’s CANbus control reduces cost of installation.

Danfoss Power Solutions Extends PVG Portfolio with New High-Flow Proportional Valves
Modular concept used in PVG 128 and PVG 256 simplifies the design process, improving time to market for OEM customers
Danfoss Power Solutions has added two high-flow proportional valves to its PVG portfolio, expanding its full range of low- to high-flow capabilities for OEM customers. The PVG 128 and PVG 256 valves are designed to easily integrate with the existing line of Danfoss high-performance proportional valves — PVG 16 and PVG 32 — to supply the hydraulic flow from low to high within the same valve stack.
“We designed the PVG 128 and PVG 256 to be compatible with the smaller valves in our PVG portfolio, meaning that if you know one valve you know them all,” said Knud Meldgaard Jensen, global product marketing manager for Danfoss Power Solutions. “OEMs can easily optimize their machine with the entire valve range, saving space, weight and costs.”
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 is also available, increasing the flow up to 500 liters (132 gallons) per minute.
“This broad flow rate range allows us to customize the exact hydraulic flow needed for the various functions of a specific use, which saves our OEM customers time when designing and developing their applications,” added Meldgaard Jensen.
Highly modular design
The new high-flow valves are designed to work in conjunction with the smaller valves in the PVG portfolio, with consistent performance through 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 every 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 have a combination linear and progressive characteristic, and the same spool can be used for all configurations with and without LS A/B relief valves.
PVG 128 and PVG 256
Features and benefits of the high-flow valves include:
- High machine performance and productivity, due to the pre-compensated valve design.
- Adaptable to regional fitting standards and reducing costs and installation complexity with available variations to SAE- and Metric flanges as well as BSP and UNF threaded ports.
- Smooth load-independent flow control for optimum productivity and precise operation.
- Limited pressure on each valve section work port from the individual load-sensing A/B relief valves, reducing stress on the structure, improving energy efficiency and ensuring safe and reliable operation.
- Consistent control interface across the PVG portfolio and easy setup due to the same type of actuation as the PVG 32 and PVG 16, including mechanical (PVM), hydraulic (PVH), high current (PVHC) as well as CANbus control (PVED S5) with full PLUS+1® compliance.
- Optimized operator productivity through high precision and repeatability of the valve performance. This is ensured through the precise PVE S7 and PVED S5 valves, which build on the high performance of the PVG 128 and PVG 256.
- Additional diagnostics, lower cost of installation and ensured data availability on the bus through CANbus control.
- A manual control (PVM) for each valve section, allowing work to continue in the event of electrical power failure.
The new high-flow valves are ideal for use on highly demanding applications such as large mobile/truck mounted cranes, crawler cranes, ship cranes, winches, drilling machines, etc. Using the PVG 128 and PVG 256 in conjunction with smaller valves will allow OEMs in these industries to easily enhance machine performance, while improving productivity and lowering energy consumption.
