Description
The DBW30B3-5X/200S6EG24N9K4R12 limits system pressure to a value between 4 and 200 bar while relieving up to 650 l/min. The pilot stage uses a seat design, and setting is done on a lockable rotary knob with a scale.
Benefits
- Adjustment range of 4 to 200 bar, with the body rated for 350 bar operating pressure
- 650 l/min relief capacity to the ISO 6264-10-17 interface
- Lockable rotary knob with a scale for a setting that can be documented
- Seat design in the pilot stage, closing tightly at rest
- Electrical unloading through the solenoid at 24 VDC
- Subplate mounting, two ports, weight 7 kg
Applications
The usual place of installation is a hydraulic power unit of a machine tool or press running around 200 bar. Electrical unloading lets the pump work against low pressure during start-up and breaks. The lockable knob secures the value set at commissioning.
