The Bosch Rexroth M - 3SED6UK1X/350CG24N9K4 (R900052621) is a top - notch industrial hydraulic valve, engineered to switch oil flow direction with reliability. As a direct - actuated directional seat valve with spool symbol UK, it comes with a concealed manual override and auxiliary actuation, embodying advanced design in component series X.
Key Features & Design:
- High - Pressure & Flow Capacity: Handles up to 350 bar of maximum pressure and a max flow rate of 60 L/min, making it suitable for demanding applications.
- Solenoid Actuation: Precise control is achieved through solenoid actuation. Wet - pin DC solenoids with detachable coils ensure safe switching even after long - term pressurized standstill. The coils can be rotated 90 degrees and replaced without opening the pressure - tight chamber.
- Mounting & Connectivity: Designed for subplate mounting, it conforms to NFPA T3.5.1 R2 D03 and ISO 4401 standards. Its size 6 CETOP interface and EN 175301 - 803 compliant electrical connector (Connector pole + PE) enable easy integration.
Technical Advantages:
- Versatile Fluid Compatibility: Works with various hydraulic fluids like HL, HLP, and HFC, expanding its application scope.
- Durable Construction: NBR seals ensure long - lasting performance in different conditions.
Applications
- Ideal for industrial machinery such as presses, injection molding machines, and metal - working equipment where accurate flow direction control is crucial.
Why Choose M - 3SED6UK1X/350CG24N9K4?
- Reliability: Robust construction and safe actuation mechanisms guarantee consistent operation.
- Efficiency: Direct operation and solenoid actuation offer an efficient fluid flow control solution.
In conclusion, the Bosch Rexroth M - 3SED6UK1X/350CG24N9K4 is a reliable and efficient choice for precise hydraulic flow direction control in industrial settings.
