Core Function

Maintains constant output pressure from the plunger pump (i.e., “constant pressure control”). When system pressure reaches the set value, it automatically adjusts the pump displacement to prevent pressure overload while stabilizing system pressure.

Suitable Applications

Compatible with Rexroth A10VSO28 series axial piston pumps, primarily used in hydraulic systems of construction machinery such as concrete PUMP TRUCKs, excavators, and Loaders.

Key Features

A pilot-operated pressure control valve. System operating pressure is set by adjusting the top adjustment screw. Typically constructed of cast iron, it offers high-pressure resistance (operating pressure up to 35MPa) and impact resistance.
