DBW10B1 Series Valves OVERVIEW

DBW10B1 is an NG10 two-stage pilot-operated electromagnetic relief valve, fully compatible with Rexroth standard DBW series. It integrates system pressure limiting, pressure regulation and electromagnetic remote unloading functions. With stable pressure holding and low noise, it serves as core pressure control components for open hydraulic circuits.

Our valves adopt standard ISO subplate installation, supporting multiple control oil forms. All internal parts are precisely machined, interchangeable with original brands, and complete repair kits are available for after-sales maintenance. Widely matched with hydraulic power units, machine tools, injection molding machines, construction and agricultural machinery.

DBW10B1 Series Valves FAQ:

1. What is the DBW10B1 Series Valves ?

• Two-stage concentric poppet structure delivers precise pressure control, small pressure fluctuation and low running noise, with fast dynamic response and minor pressure impact during unloading.

• Integrated solenoid valve realizes automatic remote unloading to cut system energy loss, supporting multi-stage pressure regulation for different working cycles.

• It bears max 315 bar pressure and handles flow up to 200 L/min, with cast internal flow channels for strong flow capacity.

• Multiple configurable options: DC24V/AC220V solenoids, NBR/FKM seals, internal/external control & drain modes, lockable pressure adjustment knobs.

• Fully interchangeable with original Rexroth DBW10B1; all internal spare parts are supplied for easy overhaul.

• Compact heavy-duty valve body fits ISO standard subplate mounting, reliable for long-term heavy-load use in industrial, construction and agricultural machinery.
  
  

3. What is the working pressure range of DBW10B1 Series Valves ?

• Adjustable pressure range: 5 ~ 315 bar (0.5 ~ 31.5 MPa) for system pressure regulation.

• Max working pressure of main oil ports (P, A, B, X): 315 bar (31.5 MPa), peak withstand pressure up to 350 bar.

• Drain port back pressure limit: Max 200 bar for DC solenoid; max 160 bar for AC solenoid.

4. Can DBW10B1 Series Valves replace other brands?

5. What hydraulic oil is recommended for DBW10B1 Series Valves ?

• DBW10B1 is a pressure control valve without rotating components, so there is no rated input speed like hydraulic pumps or motors.Its applicable flow range is 0 ~ 200 L/min. It can work stably under the matching flow of the hydraulic system, and is not limited by rotational speed.
