TTS Type Control Valve Block for Hatch Cover

Core Functions and Applications
Marine hatch cover control valve blocks act as the control hub of the hatch cover hydraulic system. They precisely adjust the flow, pressure, and direction of hydraulic oil, ensuring smooth opening and closing of TTS, MacGregor, and SEOHAE hatch covers. This proactive regulation prevents operational failures like jamming and leakage, supporting efficient and safe cargo handling at ports.

Product Detail

PRODUCT ADVANTAGES

  • Anti-Corrosion Coating: The valve body features a nickel plating + painting finish, achieving salt spray corrosion resistance of more than 1000 hours to withstand marine harsh conditions.
  • Standardized Precision Processing: Manufactured using CNC machining centers, with a hole position accuracy error of ≤0.02mm. Internal surfaces undergo fine grinding to eliminate burrs, and all components are ultrasonically cleaned pre-assembly to avoid valve jamming due to contaminants.
  • Complete Traceability System: Each valve block’s production records, technical drawings, test results, and after-sales data are retained, enabling convenient customer traceability.
  • 2-Hour Fault Response: Remote diagnostic solutions are provided within 2 hours of customers reporting valve block problems, ensuring quick troubleshooting.

 

 

COMPATIBLE BRANDS AND SERVICE CAPABILITIES

  • Maintenance & Calibration Services: We offer sandblasting for rust removal, seal replacement, and pressure/flow calibration. Post-maintenance, valve blocks are tested under simulated real-ship operating conditions to ensure pressure and flow control accuracy matches the original vessel’s standards.
  • Original Drawing-Based Production: We produce valve blocks in strict accordance with original ship drawings for TTS, MacGregor, and SEOHAE, using components from renowned international brands (PARKER, REXROTH, HYDAC) to ensure high reliability and performance.
  • Obsolete Valve Retrofit: For original ship valves that are out of stock (e.g., old cartridge valves, directional valves), we provide retrofit designs based on original parameters—reducing modification costs by 80% and delivering in 3–5 days.
