HSZ06A433-3X/PRDB-LBN-K1CG24N9K4M01

The HSZ06A433-3X/PRDB-LBN-K1CG24N9K4M01 sandwich plate is manufactured by Bosch Rexroth for the HSZ Sandwich Plates series and serves as a pressure-control element in hydraulic automation stacks. It withstands a maximum operating pressure of 315 bar, enabling use in high-pressure circuits without risk of deformation. A factory pressure setting of 14 bar provides a preset relief point that speeds initial system setup. The pressure can be adjusted with a hex setscrew, allowing technicians to fine-tune the valve directly on site. Directional valve symbol C defines the internal flow path so designers can place the plate correctly in the schematic. The DIN 24340 Form A mounting pattern aligns with common subplates, simplifying manifold integration. Compact dimensions of 170 × 44 × 70 mm fit limited cabinet spaces, and a weight of 4.5 kg keeps manual handling straightforward during installation.

The solenoid operates on 24 V DC, matching typical machine control power and removing the need for auxiliary converters. A coil power rating of 22 W supplies adequate magnetic force while keeping heat generation moderate. Coil type GZ37-4 is selected to deliver consistent actuation characteristics over the full pressure range. Electrical connection is made through a DIN EN 175301-803 K4 plug, providing quick coupling and IP-rated sealing against fluid ingress. A concealed manual override labeled N9 lets maintenance staff shift the spool during power loss while guarding against accidental use. NBR seal material resists common hydraulic oils and maintains elasticity under pressure cycling. External surfaces carry a Fe//Zn8//Cn//T0 coating to DIN 50979, adding corrosion resistance in humid or oil-spray environments.
