Pressure Relief Valve DBW20B2-5X/200YS6SMG24N9K4B12V/12 - Bosch Rexroth R900964495

A power unit that has to stay limited to 200 bar while its pump is unloaded on start-up needs exactly this combination of relief function and solenoid unloading. The pilot-operated poppet valve in size 25 handles 500 l/min and withstands an operating pressure of up to 350 bar.

Benefits

• pressure setting range 4 to 200 bar via internal hexagon with protective cap
• 500 l/min flow in size 25
• 350 bar maximum operating pressure, two ports, spool symbol B
• solenoid unloading on 24 VDC, connector 3-pole (2 + PE) to EN 175301-803
• connection diagram ISO 6264-08-13, FKM seals, 5.46 kg

Application

The valve sits at the pump of presses, injection moulding machines and test benches whose consumers are rated for 200 bar. Solenoid unloading takes the load off the pump on start-up and during idle phases. FKM seals allow service at higher oil temperatures.
