Pressure Relief Valve DBW20BG2-5X/315-6EG24N9K4VSO631 - Bosch Rexroth R900936442

At raised oil temperature or with special hydraulic fluids, the seal material becomes the decisive feature. This pilot-operated size 25 pressure relief valve is fitted with FKM seals, covers 3.8 to 315 bar and passes up to 500 l/min.

Benefits

• FKM seals instead of NBR, rated for higher oil temperatures.
• Setting range of 3.8 to 315 bar against a maximum operating pressure of 350 bar.
• Threaded connection to connection diagram ISO 6264-08-13, installed without a subplate.
• Solenoid unloading through a built-on directional spool valve at 24 VDC.
• Internal hexagon under a protective cap secures the setting.
• 500 l/min maximum flow at 6.74 kg weight.

Technical data

Application

Intended for installations at raised operating temperature, for example in foundries, hot forming and test benches with long load cycles. The high setting range allows high-pressure stages to be protected. The solenoid section switches the circuit to zero pressure during pauses.
