A power unit passing 2000 l/min cannot be unloaded through a small valve. The DBW52BF2-3X/315U6EG24N9DALV limits pressure up to 315 bar, unloads through a built-on solenoid valve and is adjustable between 3.9 and 315 bar.

Large pump units have to circulate without pressure at start and during breaks, otherwise every minute costs energy. The pilot operated pressure relief valve DBW52 in size 52 handles both, limiting system pressure to 315 bar and switching to unloading through a built-on directional valve, at up to 2000 l/min.
Benefits
- 2000 l/min maximum flow suit units running several large pumps.
- Solenoid unloading through a built-on directional valve, without an extra bypass valve.
- An adjustment range of 3.9 to 315 bar covers start and working pressure in one valve.
- Poppet seat design keeps leakage low, and the internal hexagon is secured by a protective cap.
- Flange connection in size 52 for large line cross sections.
- A 3-pole (2 + PE) plug according to EN 175301-803 at 24 VDC, with a cable gland at the solenoid.

Application
The valve goes into central power units of press lines, rolling mills and hydro power plants. Unloading cuts starting torque and waste heat because the pump delivers against low pressure. At 29.12 kg with a flange pattern, proper support of the piping has to be provided.
