Pressure Relief Valve DBW30BG2N5X/200Y6EG24N9K4E - Bosch Rexroth R901000553

A piped circuit with a large pump needs a valve that takes the full flow and lets the pilot oil drain separately. This pilot-operated pressure relief valve has three ports, covers 3.8 to 200 bar and accepts up to 700 l/min.

Benefits

• 700 l/min permitted flow with a setting range of 3.8 to 200 bar.
• Threaded connection with three ports, the third allowing separate drainage of the pilot oil.
• Internal hexagon under a protective cap, so the value stays fixed after commissioning.
• Solenoid unloading through a built-on directional spool valve at 24 VDC.
• Pressure valve in poppet seat design with tight closing at rest.
• 6.5 kg weight at a maximum operating pressure of 350 bar.

Application

Intended for piped power units, forming lines and central supplies with high delivery. The separate pilot drain helps when the return line carries back pressure. During pauses the solenoid section switches the circuit to zero pressure, with approval for HL hydraulic fluid and NBR seals.
