The proportionalDirectional spool Series type PSL from Hawe Hydraulics became one Onboard electronics Option extended. Pressing CAN Lite offers an entry into the CAN bus Communication for many Mobile Machinery at. Manufacturers who have implemented quick commissioning through low cabling costs and preset parameters are addressed here.

Switching from directional valve control to CAN bus

By switching from the Valve control With pulse width modulation (PWM) on the CAN bus, the valves can be precisely addressed and function parameters can be easily adjusted. The start and end positions of the directional spool are preset in the delivery state for easy commissioning. The typical hysteresis for directional spool valves is very low with the PSL-CAN Lite. The valve manifold is connected to the bus system with just one connector. Of the Cabling effort is low and commissioning will be shorter.

The CAN-Lite actuation can be combined with the fully equipped CAN actuation version with feedback of the slide position from Hawe in a valve bank. Depending on the required precision and repeatability, the machine builder decides which type of actuation is best for each consumer.

The proportional directional spool valve PSL allows operating pressures of up to four sizes 420 bar and a volume flow of 1 to 1000 l / min. The different sizes can be combined in a valve bank. If only the size required for the respective individual function is used in the valve bank, the weight is reduced and the fine control is improved.
