Pressure Drop is Profit Drop
Generic aftermarket valves suffer from internal leakage and coil burnout when exposed to the thermal spikes of a Sany reach stacker’s duty cycle. A 10% pressure drop in your main control valve means slower lifting, higher fuel consumption, and operator fatigue.
Zhenke Hydraulics eliminates this. Our valve bodies are machined from high-tensile cast iron, honing tolerances to within 2 microns. We install Viton seals standard, ensuring compatibility with synthetic hydraulic fluids at temperatures up to 120°C.
Solenoid Response Time
< 20ms activation speed preventing signal lag.
IP69K Coil Protection
Fully sealed against high-pressure washdowns.
Surviving the “Water Hammer” Effect
In hydraulic circuits, sudden valve closures create shockwaves (water hammer) exceeding 400 Bar. Cheap cast-iron bodies crack under this fatigue. Zhenke valves utilize QT500-7 Ductile Iron, providing the tensile strength needed for Kalmar heavy lifting operations.
