Optimizes Productivity

Low-flow PVG 16 covers simple to complex needs. Proven technology and components for customized valve stacks. Benefit from load-sensing functionality made for the low-flow segment. PVG 16 optimizes productivity, lowers total system costs and facilitates fulfilment of emissions and safety regulations. Use with the PVE series 6 actuator for seamless integration in advanced electrohydraulic systems.

 

PVE series 6 actuator

Incorporating a microcontroller for closed loop control, PVE series 6 delivers excellent spool control and built-in fault monitoring to the PVG 16. High tolerance towards temperature variations ensures a robust, reliable valve performance in all conditions.

 

Key Applications

PVG 16 targets on a broad range of applications in the mobile machinery market. Typical applications are municipal vehicles, agricultural machinery, small cranes, construction machinery and road building applications.

 

Lower Total System Costs – machine benefits

  • Optimized system architecture and unique machine features due to design flexibility and modular concept.
  • Improved efficiency obtained by precise matching of performance with flow requirements.
  • Reduced cooling and fuel requirements.
  • Low machine downtime supported by high quality products, modular concept and advanced product feedback.
  • Optimized production processes and less inventory due to modular concept and short delivery time.

 

Product Features

  • Flow rating up to 65 l/min [17.2 US gal/min].
  • Work port pressure up to 400 bar [5,800 psi].
  • Actuator with integrated float function for increased safety.

Maximum Flexibility

The Danfoss flagship PVG 32 is designed for maximum flexibility. Proven 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 our PVE electrohydraulic actuators.

 

Load-Sensing

By using PVG load-sensing technology in combination with a variable displacement pump, it’s possible to achieve a significant reduction in energy loss. 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.

 

OEM and Machine Benefits

  • Modular design, providing a wide range of configuration possibilities.
  • Load-independent flow control for precise operation and improved productivity.
  • Load-sensing technology for higher efficiency, safety, reduced energy consumption, and longer system life.

 

Product Features 

  • Configurable as advanced electrically controlled proportional valve as well as load sensing directional control valve.
  • Prevention against work port pressure build up.
  • Individual work port pressure setting.
  • Zero-leakage work modules.
  • Open center and closed center versions available.
  • Modular design, which can be combined with PVG 100, PVG 120, PVG 16 and PVG 128/256.

 

 

PVG 128/256 Proportional Valves

Modularity and Efficiency

For the most demanding applications, only the highest flow and the highest pressure will do. The PVG 128/256 are built to take control with up to 500 l/min per section supplied with up to 1200 l/min (300 US gal/min) pump flow.

 

Rock-solid control and optimum safety are more critical than ever when it comes to the biggest applications and the heaviest tasks. This new proportional (pre-compensated) load-sensing valve series can easily be built together with PVG 32 and PVG 16 making it easy to build a valve that is adapted to the flow needs of the most demanding application.

 

Application Opportunities

Go with our PVG 128/256 and optimize work functions on cranes, mining, drill rigs and marine applications like winches and bow thruster.

 

Machine Benefits

  • Smooth load-independent flow control for optimum productivity and precise operation.
  • Energy-efficient load-sensing technology for maximum safety and a long system life.
  • CAN bus control for lower installation cost and increased diagnostics.

 

Product Features

  • Optimized for lower pressure drop and higher efficiency.
  • Compact sectional platform solution for easy integration with PVG 16 and PVG 32.
  • Compact design, easy installation and serviceability.
  • Individual LS A/B relief valves ensure energy efficient, safe and reliable operation.
  • Mechanical actuation as default on all valve sections.
  • Hydraulic actuation.
  • Electrohydraulic actuators PVE (Ratio metric, 0-10V, CANbus) as well as PVHC (High Current PWM) actuators.

 

The Danfoss PVG portfolio also includes the PVG 100 and the PVG 120.
