Low-Flow Load-Sensing Hydraulic Valve

Posted on January 31, 2013

Sauer-Danfoss has developed the first load-sensing valve in its portfolio for the low-flow segment. The new PVG 16 valve facilitates the integration of load-sensing system design and electrohydraulic actuator technology.

Based on Sauer-Danfoss’ existing PVG technology and components, the PVG 16 is rated for a flow of up to 65 l/min [17.2 gpm] and work port pressure of up to 400 bar [5800 psi]. Municipal vehicles, agricultural equipment, small cranes and construction machinery are among the key applications listed by Sauer-Danfoss.

The PVG 16 is seen by Sauer-Danfoss as the next step for its PVG technology platform. Along with its modular design – characteristic of the entire PVG family – the valve makes use of established building blocks in the PVG design toolbox.

For example, the pump inlet module and endplate are identical to those of the PVG 32, preparing the PVG 16 for integration in customized valve stacks, accommodating everything from simple to complex functionalities.

A new actuator – the PVE Series 6 – provides the valve with its electrohydraulic platform. Incorporating a microcontroller for closed loop control, the actuator delivers spool control and built-in fault monitoring, with what Sauer-Danfoss says is high tolerance towards temperature variations.
