Repair/Overhaul Hydraulic Valve Blocks
Core Functions and Applications
Hydraulic valve blocks serve as the control core of hydraulic systems for ship anchor windlasses, mooring winches, deck cranes, and hatch covers. The repair and overhaul service targets faults in valve blocks of brands such as TTS, MacGregor, and SEOHAE—including seawater corrosion, valve jamming, seal leakage, and pressure loss. Through disassembly, repair, and calibration, the service ensures valve blocks accurately control the flow rate, pressure, and direction of hydraulic oil, preventing port detention accidents caused by valve block failure (e.g., inability to open/close hatch covers or operate anchor windlasses for chain handling). It is suitable for the maintenance of deck hydraulic systems on various merchant ships and special-purpose vessels.
