Pressure Relief Valve DBW20AG3-5X/315S6EG24N9K4R12V - Bosch Rexroth R900928752

A threaded connection saves the subplate and the height it takes up inside the power unit. The pilot-operated DBW20AG3-5X/315S6EG24N9K4R12V uses that connection in size 25, holds pressure between 3.8 and 315 bar and lets up to 500 l/min flow off.

Benefits

• Threaded connection in size 25, no separate subplate required
• Electrical unloading through a built-on directional spool valve at 24 VDC
• Setting range 3.8 to 315 bar on a lockable rotary knob with scale
• Relief flow of up to 500 l/min, maximum operating pressure 350 bar
• Weight of 7.01 kg, pressure valve in poppet seat design with FKM seals

Technical data

Application

The built-on solenoid switches the circuit pressureless while the pump keeps turning. In cycled operation that lowers oil heating and power draw during the pauses. The threaded connection makes the valve a candidate for retrofits where no matching subplate exists. At 500 l/min relief flow it also covers larger power units.
