Product Overview

The Bosch Rexroth Pressure Cut-Off Valve is a genuine OEM high-precision hydraulic control valve designed to protect closed-circuit hydrostatic systems from over-pressurization. Built precisely for the Rexroth A4VG125 and A4VG180 series pumps, this valve monitors system pressure and automatically moves to a closed position when a mechanically set limit is met. Configured with a 50 Nm (#50NM) factory calibration specification, it safely bypasses excessive pressure to the reservoir, preventing internal damage and restoring smooth, predictable operation to high-capacity heavy machinery.
