Pressure Relief Valve DBW20B2-5X/195Y6EG24N9K4E - Bosch Rexroth R900788021
A safety valve has to match the rated pressure of the plant, not the next standard step up. The DBW20B2-5X/195Y sets between 4 and 195 bar, passes 450 l/min through an ISO 6264-08-13 subplate pattern and weighs 5.3 kg.

Description
The DBW20B2-5X/195Y6EG24N9K4E covers a setting range of 4 to 195 bar, which suits plant rated just under 200 bar. It passes 450 l/min, holds a maximum operating pressure of 350 bar and is switched to unloaded circulation by a 24 VDC solenoid.
Benefits
- Setting range 4 to 195 bar, matched to plant rated around 200 bar
- 450 l/min at 350 bar maximum operating pressure, size 25
- Pilot-operated poppet valve, 2 ports, subplate mounting to ISO 6264-08-13
- Electrical unloading on 24 VDC through a 3-pole connector (2 + PE) to EN 175301-803
- Internal hexagon under a protective cap, NBR seals, 5.3 kg
Application
It protects power units in machine tools and conveying equipment designed for just under 200 bar. Because the setting range ends there, the value cannot be wound past the plant limit by mistake. Subplate mounting keeps the pipework untouched during a swap.
Manufacturer
Bosch Rexroth, material number R900788021. Two manufacturer documents are supplied, setting curves are given in data sheet RE 25802.
