Product Overview
▔▔
The Rexroth 0811402019 relief valve is engineered to automatically limit the maximum pressure in a hydraulic circuit. When system pressure exceeds the preset value, the valve opens and redirects excess fluid, preventing damage to pumps, actuators, and pipelines.
Key Advantages
▔▔
- Precise proportional pressure control
- Electrical control for automation systems
- High reliability in industrial environments
- Fast response and stable performance

FAQ
▔▔
How does the Rexroth 0811402019 relief valve regulate pressure precisely?
The valve uses a spring-loaded mechanism combined with a pressure sensing element. When system pressure exceeds the preset value, hydraulic force overcomes the spring force, opening the valve. The design ensures smooth modulation rather than abrupt opening, which allows for stable and precise pressure control even under dynamic load conditions.
What is the recommended filtration level for optimal performance?
To ensure long service life and stable operation, a filtration level of NAS 6–9 or ISO 4406 class 18/16/13 or better is recommended. Contaminated oil can cause sticking, wear, and inaccurate pressure control.
