Total price
A back pressure of only a few bar can be held accurately only with a correspondingly soft spring. The pilot-operated DBW30B2-5X/50US6EG24N9K4R12 therefore works from 2 to 50 bar while passing up to the 650 l/min of size 32.
Benefits
- Adjustment range 2 to 50 bar, sensitive setting in the lower pressure band.
- 650 l/min rated flow, the return line is not throttled even at high oil volumes.
- 350 bar permitted operating pressure, the body withstands spikes from the main circuit.
- Symbol B with two switching positions, switched electrically from 24 VDC.
- 7.04 kg, subplate mounting ISO 6264-10-17, internal hexagon with protective cap.

Applications
The valve builds back pressure and holding pressure in presses, lift tables and machine tools. A low adjustment range keeps the return from damming up needlessly and turning energy into heat. The solenoid lets the back pressure be switched off from the control system.
