Sauer-Danfoss launches low-flow, load-sensing hydraulic valves

Sauer-Danfoss has developed the first load-sensing valve for low flow range. The new PVG16 valve facilitates the integration of load sensor system design and electro-hydraulic actuator technology.

Developed from Sauer Danfoss' existing PVG technology and components, the PVG16 is rated for up to 17.2 gallons / minute and working port pressures up to 5800 psi. Sauer-Danfoss said the hydraulic valves are mainly used in municipal vehicles, agricultural equipment, small cranes and construction machinery.

Sauer-Danfoss PVG product marketing manager, said: "to meet the emission control and functional safety requirements under the premise of the hydraulic equipment to achieve higher efficiency, you need advanced system design and performance to achieve.Therefore, the use of load transfer The advantages of sensing the valve are obvious, that is more durable, more energy efficient, superior controllability and safety.

Sauer-Danfoss The new PVG16 is a low-flow, load-sensing hydraulic valve rated at 17.2 gallons / minute with a working port pressure of up to 5800 psi for municipal vehicles, agricultural equipment, small cranes and construction mechanical.

Sauer-Danfoss sees the PVG16 valve as the next step in a PVG technology platform development strategy. With the modular PVG16 valve design, valves can be designed using established modules in the PVG design database.Control Valve, Flow Control Valve, Hydraulic Control Valve, Proportional Directional Control Valve

For example, PVG16 valve pump inlet module and end plate the same size and PVG32 PVG16 valve through the custom valve manifold integration, from simple to complex to achieve all the features.

Clausen said: "From a cost and efficiency point of view, the valve banks need to be set up to meet the flow requirements for each function of the machine." The modularity of the low-flow PVG16 valve allows for more precise functional matching than ever before. "

PVE6 is a new type of actuator that provides an electrically controlled hydraulic platform for the control valve. The actuator incorporates a microcontroller closed-loop control that enables spool valve control and embedded fault monitoring and high temperature resistance monitoring of temperature changes.

Sauer-Danfoss PVG valve series also includes PVG32, PVG100 and PVG120, providing flow rates up to 63.4 gallons / min.
