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.
