Danfoss PVG 32 Proportional Valves

 Maximum Flexibility:

The Danfoss PVG 32 Proportional Valve is designed for maximum flexibility. Proven Danfoss PVG technology that saves you time. No matter which combination of valves is specified, the compact, external dimensions of the valve remain unchanged. Advanced electronic control can be achieved with Danfoss PVE electrohydraulic actuators.

 

Load-sensing:

By using Danfoss PVG load-sensing technology in combination with a variable displacement pump, it’s possible to achieve a significant reduction in energy loss. Danfoss PVG Valves also reduce heat generation and increase efficiency and power density, which helps OEMs to meet the challenges posed by new diesel engine emissions legislation.

• Modular design, which can be combined with PVG 100, PVG 120, PVG 16 and PVG 128/256.

 

Danfoss PVG 100 Proportional Valves

 High Performance:

Enjoy the flow-sharing functionality of the Danfoss PVG 100 Proportional Valve – more performance with less horsepower under any conditions.

The flow-sharing technology of the post-compensated, load-sensing Danfoss PVG 100 is ideal in systems where flow demand regularly pushes supply to the limits.

The modular Danfoss PVG range is designed for maximum flexibility.

 

New Danfoss PVG 100 high flow options tackle the heaviest loads:

The new Danfoss PVG 100 high flow post-compensated valve raises port flows with less work - pump margin of 15 bar [217 psi] - and lowers the return pressures. PVG 100 high flow options meet the increased demands for high efficiency and high flow solutions.

 

Sharing The Flow:

The Danfoss PVG 100 Valve distributes flow to multiple machine functions proportional to their load and flow requirements. As such, when demand exceeds supply each function remains up and running – on proportionally less flow. In the face of tougher emissions laws, there really is no better way to improve performance with less power and reduced energy consumption. 

 

Machine Benefits include:

• Flow sharing for optimum controllability and user-friendliness. 
• Load-independent flow control for precise operation and improved productivity.
• Load-sensing technology for higher efficiency, safety, reduced energy consumption, and longer system lifetime. 

 

Product Features include: 

• Modular design, which can be combined with PVG 32.  
• Post compensated flow sharing valve. 
• Open spool-ends for mechanical actuation. 
• Optimised return flow characteristics, which minimises pressure loss.
