<\/strong>Despite the fact that water is rarely used in power-control hydraulics (PCH), advanced technologies such as 3D printing of metal components are opening new possibilities for the wider adoption of water PCH. With metal 3D printing, valve mass can be significantly reduced while improving flow characteristics, thanks to the ability to produce complex internal geometries not achievable with traditional methods. In this study, we designed and tested a spool valve produced using 3D printing and explored new materials for control pistons, which are crucial for the operation of water-hydraulic systems. Tribological tests allowed us to examine various material pairs and measure friction and wear coefficients, helping us identify the most suitable materials for use in water hydraulics. Additionally, we developed a testing rig for durability testing of valves, which allowed us to evaluate their longevity and reliability under real operating conditions. Our research opens new avenues for the development of improved water-hydraulic systems, contributing to the advancement of this rarely used but potentially significant technology.<\/p>\n
