Product Overview
The Rexroth ABZSS 30 E-3X/330E/S309G24K4V (Material Number R900709657) is a high-performance accumulator safety block designed for hydraulic systems requiring reliable pressure control and safe isolation of bladder, piston, and diaphragm accumulators. As a specialized pressure control valve assembly, this unit combines multiple functions—manual shut-off, pressure relief, and controlled unloading—into a single compact block. It is engineered to protect hydraulic circuits from overpressure while enabling safe maintenance and controlled depressurization of the accumulator. The ABZSS series is widely used in industrial hydraulic power units where accumulator safety and precise pressure management are critical.
