Parker introduces steer-by-wire valve for mobile machinery applications

Over the years, orbitrol steering has become a de facto standard in mobile machinery. The orbitrol solution has many benefits and it is a proven and reliable system. However, there are disadvantages with the orbitrol steering system. A Steer-by-Wire system where the hydro-mechanical connection between the steering wheel and the steering cylinders is substituted with electronics enables a hydraulic-free cabin, easier installation, and increased comfort for the operator.

Steer-by-Wire systems are compatible with other automotive trends such as vehicle automation (autono-mous driving), remote connectivity and artificial intelligence. These advantages also bring high energy efficiency.

The Parker SBW110 mobile directional control valve is a state-of-the-art closed center load sensing (LS) valve. The valve is controlled by two individual pilot circuits. The pilot circuits consist of fail-safe pilot valves. With a proportional control pressure rating up to 350 bar and pressure compensated flow up to 110 l/min, it is well-suited for mobile machinery applications.

The SBW110 valve is designed according to ISO 13849-1:2015 and ISO 13849-2:2012 with design architecture category 3 (single fault tolerant), and the requirements in ISO 5010:2019 for rubber tyred machines and can be used in systems requiring PL a to PL e.
