Product Description
Rexroth R901353030 DBEM20-71/200XYG24-8K4M
The Rexroth R901353030 DBEM20-71/200XYG24-8K4M is a pilot-operated proportional pressure relief valve designed to limit the pressure in a hydraulic system. It features integrated On-Board Electronics (OBE) for precise and continuous pressure adjustment based on an electrical command signal. This model is typically used in applications requiring dynamic pressure control, offering a maximum pressure setting of 200 bar. It includes a 24V DC solenoid, a K4 type electrical connector for easy installation, and a manual override feature for operational flexibility or emergency adjustments. The valve’s design ensures reliable performance in various industrial hydraulic systems.
