The Bosch Rexroth SFA80F1-1X/M/01 (R900737034) is a sophisticated pilot operated check valve designed for both threaded and flange connections, catering to a wide range of hydraulic applications. This particular model is adept at ensuring stability and control in hydraulic systems by allowing flow in one direction and preventing reverse flow until pilot pressure is applied. It stands out due to its capability for direct attachment to working cylinders, which enhances its efficiency and ease of integration into various systems. The valve comes with the option of having predecompression or not, which can be specified based on the requirements of the application. The inclusion of an integrated high-pressure port further adds to its versatility. With its size tailored for optimal performance, the SFA80F1-1X/M/01 operates effectively within its maximum operating pressure of up to 350 bar and can handle a maximum flow rate that ensures it meets the demands of even the most challenging fluid control tasks. Engineered for reliability and precision, this model belongs to component series X, indicating its adherence to current engineering standards and innovations by Bosch Rexroth. Users can expect consistent performance and durability from this check valve, making it suitable for a variety of industrial applications where fluid control is paramount. Whether utilized in manufacturing equipment, mobile machinery, or any other system requiring meticulous hydraulic control, this Bosch Rexroth check valve provides a solution that engineers and technicians can depend on for both functionality and quality.

For limit areas, please contact us. It is often enough, to select a pipeline which is one size larger.
Attention!
An underdimensioned prefill valve and/or an underdimensioned line leads to gas leaks from the hydraulic fluid with corresponding consequences and often to long-term damage at the cylinder seals.
