Description
Up to 400 bar at flow rates up to 120 l/min, the pressure relief valve DBDS8G1X/400 in size 8 protects the hydraulic circuit. DBDS8G1X/400 reliably limits system pressure to the setting and protects pump, lines and actuators against overload.
Benefits
- Up to 400 bar: DBDS8G1X/400 is rated for this maximum operating pressure.
- 120 l/min flow: maximum throughput in size 8.
- Pipe thread G 3/8 to ISO 228-1: DBDS8G1X/400 installs directly in the line.
- NBR seals: DBDS8G1X/400 is suitable for hydraulic fluid HL, HLP, HLPD, HVLP, HVLPD, HFC.
Applications
Protection of pumps, cylinders and hydraulic motors in industrial hydraulics. For replacement orders, type DBDS8G1X/400 and material number R900427603 allow a reliable match with the existing valve.
