APB

The APB series was developed to meet the needs of tractor manufacturers equipped with the Power Beyond system, which consists of a separate hydraulic circuit powered by a variable flow pump equipped with a Load Sensing system.

Stucchi’s flat face female couplings are designed according to the Power Beyond standard: ISO17567:2020 for class 2 and are available for pressure lines, return lines, drainage, and load sensing.

Benefits

  • Developed according to the Power Beyond standard: ISO17567:2020 (Flow class 2).
  • The patented front seal prevents dirt particles from entering the circuit, eliminating the need for protective caps.
  • The flat face is easy to clean, reducing the inclusion of contaminants within the hydraulic circuit.
  • Breakaway function to prevent damage to hydraulic connections in case of strong axial force during unintended disconnection.
  • Line P equipped with a patented pin locking system that prevents connection if pressure inside the circuit exceeds 6 bar (prevents operator from connecting if tractor engine is running).
  • Line P equipped with pressure release valve system allows easy connection with internal residual pressure (below 6 bar).
  • Minimal fluid leakage during disconnection, reducing fluid loss into the environment.
  • Minimal air inclusion during connection.
  • Modular design allows flexibility with a wide range of configurations.
  • Zn-Ni plating ensures high corrosion resistance.
  • Good resistance to pressure impulses.
  • Safe and easy to use.
