Pressure Relief Valve DB52F2-3X/315YUV - Bosch Rexroth R900900185
Back pressure in the tank line shifts the relief setting. The DB52F2-3X/315YUV therefore drains through a third port of its own, sets 3.9 to 315 bar and handles up to 2000 l/min at the size 52 flange connection.

Description
A separate drain return keeps the pilot circuit clear of tank pressure. The pressure relief valve DB52F2-3X/315YUV carries a third port for this, works in a range of 3.9 to 315 bar and relieves up to 2000 l/min through the size 52 flange.
Benefits
- Three ports with a dedicated line for the drain return.
- Adjustment range of 3.9 to 315 bar, maximum operating pressure 315 bar.
- Flow up to 2000 l/min in pilot-operated poppet design.
- Internal hexagon with protective cap for the pressure setting.
- 27.41 kg in weight, FKM seals, wired via a 3-pole connector (2 + PE).
Applications
Its place is the main circuit of presses and power units where back pressure in the tank line would disturb the pilot stage. The separate return keeps pilot pressure steady even when filters and coolers build up back pressure in the tank circuit.
