Description

The ATOS Cartridge pressure relief valves type CART are versatile components used in hydraulic systems to safeguard against excessive pressure. Available in models like M-3, M-4, M-5, M-6, ARE-15, and ARE-20, these valves offer different pressure ranges and options. They can be configured with leak-free execution (R), lead-sealed regulation (RS), or manual override. The valves are compatible with various fluids and operating conditions, making them suitable for a wide range of applications. The datasheet provides detailed information on dimensions, materials, and performance characteristics, enabling users to select the appropriate valve for their specific requirements.

Technical Considerations

• Operating pressure range varies by model. • Flow capacity depends on valve size and application requirements. • Wide temperature range for diverse environments. • Compatible with various hydraulic fluids. • High-quality sealing materials for leak prevention.

Applications

• Mobile equipment (construction, agriculture, off-highway vehicles) • Industrial machinery (press brakes, injection molding machines) • Hydraulic power units

Selection Criteria

• Maximum system pressure • Required flow capacity • Environmental conditions • Fluid compatibility • Mounting options
