Which risk increases when spool valves in a hydraulic transmission tower surge tank system lack fast-acting check valves?

💡 Explanation

Water hammer events occur due to rapid fluid deceleration when valves close quickly; thus fast-acting check valves prevent backflow by hydraulic lock mitigation. This mitigation stops the accelerated reverse-flow momentum, because without them, pressure surges increase, therefore raising the risk, rather than decreasing it.
