TRANSCRIPT

PVG is a hydraulic, load-sensing proportional valve,designed for optimal machine performance andmaximum design flexibility.

The PVG 128 and PVG 256 are new members of thePVG product platform.

PVG 128 and PVG 256 controls work port flow up to500 l/min and up to 420 bar work port pressure.

The PVG valve design is based on a modular conceptthat enables machine designers to specify a valvesolution suitable for multiple market segments acrossmultiple applications.

The load independent proportional control valve andhigh performance actuator technology combinedwith a low pressure drop design improves themachine performance and efficiency—Increasingproductivity and reducing energy consumption.

General features
