HAWE Hydraulik SE, Munich, now offers its proportional directional spool valve type PSL with CAN-BUS interface in a new construction size. The valve, which features integrated electronic control, has proven successful in practice in its geometrically smallest size. This opens the way for applications that require a volume flow of up to 120 lpm: for example, municipal vehicles, mobile cranes, heavy load vehicles, and lifting platforms.
The integrated cable duct takes up less installation space than typical commercial daisy-chain models, and guarantees secure installation in vehicles. The vehicle’s control unit is connected to the valve bank via AMP connectors that have proven their viability in numerous mobile applications. On request, HAWE Hydraulik will set the parameters of the valve bank to the customer’s specification prior to shipment. This means that the customer takes delivery of a valve control that is ready for connection and so can be quickly and easily connected to the vehicle’s control system.
The proportional directional spool valve is used in the mobile hydraulic system for controlling direction of motion and for the load-neutral, infinitely variable control of the speed of motion of hydraulic consumers. The CAN-BUS interface is integrated in the valve section. This facilitates the control of complex systems with decentralized valve islands, sensors, and actuators. It also allows hydraulic valve operating times that are nearly twice as fast as those of a conventional proportional valve. This makes the product especially attractive for steering systems. Thanks to signal feedback, high repetition accuracy is achieved and the programming of automatic processes is significantly simplified. The user can therefore rely on unfailingly precise control of their hydraulic loads. All pressurized components are constructed of steel. The valve is designed for a maximum operating pressure of 420 bar.
