Pressure Relief Valve DBW52BF2-3X/315XU6EG24N9K4 - Bosch Rexroth R901058669

A pump has to work against a fixed limit and circulate without pressure between cycles. The DBW52BF2-3X does both, limiting pressure within the 3.9...315 bar range and unloading through a directional valve mounted on top that runs on 24 V DC. The poppet seat design passes up to 2000 l/min through the flange connection.

Benefits

• Setting range 3.9...315 bar, internal hexagon with protective cap against tampering
• Flow rate up to 2000 l/min through the size 52 flange connection
• Electrical unloading through a mounted directional valve, 24 V DC
• Poppet seat design for tight closing in the blocked state
• 29 kg weight, three ports, NBR seals

Applications

The valve is installed on power units of presses, plastics machinery and test rigs that go idle between working cycles. Thanks to the protective cap the setting once found stays put. The solenoid connects through a 3-pole connector (2 + PE) to EN 175301-803.
