Comatrol

COMATROL, is part of the Danfoss Group, specialising in hydraulic cartridge valves. These compact and economical components play a crucial role in controlling fluid flow and pressure within hydraulic systems.

These valves are designed with several key features:

• Reduced Plumbing: COMATROL cartridge valves minimise the need for extensive plumbing, simplifying system design and installation.
• Fewer Leak Points: By integrating essential functions into a single cartridge, they reduce potential leak points, enhancing system reliability.
• Ease of Service: When maintenance is required, these valves can be easily accessed and replaced.
• Application Range: COMATROL valves find applications across various industries, including construction, agriculture, material handling, and industrial machinery.

Understanding the Cartridge Valve Types:

• Check Valves:
  • Allows fluid to flow in one direction and block it in the opposite direction.
  • COMATROL offers a range of check valves:
    • Standard Check Valves: Basic one-way flow control.
    • Reverse Flow Check Valves: Prevent backflow.
    • Slip-In Check Valves: Easy installation in hydraulic manifolds.
    • Inline Check Valves: Inline installation for specific applications.
• Shuttle Valves:
  • Serve two purposes:
    • Load Shuttle Valves: Used in load-sensing circuits and motor brake release.
    • Hot Oil Shuttle Valves: Divert fluid for cooling or filtering in closed-circuit hydrostatic loops.
• Relief Valves:
  • Essential safety devices that protect hydraulic systems and components.
    • COMATROL offers various relief valve types:
      • Direct-acting Poppet Relief Valves: Fast response, low leakage, and cost-effective.
      • Differential Area Poppet Relief Valves: Precise pressure control.
      • Bi-directional Poppet Relief Valves: Suitable for diverse applications.
      • Pilot-operated Spool Relief Valves: Used in complex systems.
    • Pressure Reducing Valves:
      • Limits pressure in specific areas of a circuit while maintaining overall system pressure.
      • Types include:
        • Direct-acting Pressure Reducing Valves: Economical and responsive.
        • Pilot-operated Pressure Reducing/Relieving Valves: Stable response, high-pressure capability.
    • Sequence and Unloading Valves:
      • Sequence Valves: Control flow sequence in operations like clamping and lifting.
      • Unloading Valves: Improve system efficiency by unloading pump outlets at minimal pressure drop.
    • Flow Control Valves:
      • COMATROL’s pressure-compensated flow control valves regulate flow rates precisely.
