Key attributes

Integrated Anti-Reverse & Cushioning Functions
High-quality travel motors typically integrate the relief valve with an anti-reverse valve and other features. This integrated design not only prevents the machine from rolling backward when stopped on a slope but also effectively absorbs hydraulic shocks during sudden travel stops, preventing severe impacts on the entire hydraulic system.
