The HSZ06A100-3X/H210EM00 sandwich plate is manufactured by Bosch Rexroth for the HSZ Sandwich Plates series and provides a direct-operated pressure relief function to safeguard hydraulic automation circuits. Its nominal size 6 layout supports moderate flow while the ISO 4401 interface lets it stack with standard subplates. The valve mounts on side E of the manifold, allowing orderly port orientation, and adjustment is made with a rotary knob for straightforward pressure setting. Excess pressure is diverted from port P to port T, relieving the main line without external piping. A DIN 24340 Form A porting pattern aligns with common European manifolds, and the body is supplied without locating holes to ease machining when dowels are unnecessary.
The unit withstands operating pressures up to 315 bar, suiting mobile and industrial systems running at high working levels. Its 120 mm length, 44 mm width, and 50 mm height help designers predict stack dimensions, and the 1.9 kg weight allows single-person installation. NBR seals contain mineral oil without swelling, while a Fe/Zn8/Cn/T0 coating per DIN 50979 protects the housing against corrosion. Internal channels handle all flow because the model is built with no external connections, reducing leak paths and simplifying hose routing. These features deliver a compact relief plate that integrates directly into sandwich stacks and maintains reliable pressure control.
