The Bosch Rexroth SFS200A0-1-4X (R901044401) is a high-performance industrial hydraulic valve designed for reliable blocking of oil flow at selected ports. This seat valve is pilot-operated, with a spool symbol for A and B ports, and is capable of handling a maximum pressure as specified in its product group ID. It features a number of ports suitable for various hydraulic circuits and utilizes hydraulic actuation for its operation. The SFS200A0-1-4X valve boasts a size that accommodates a significant max flow rate, ensuring efficient fluid control within the system. It employs a flange connection for secure installation and easy maintenance, with the connection diagram specifying the flange type according to EN standards. The valve is also equipped with multiple switching positions and has a weight that reflects its sturdy construction. Seals made from NBR (Nitrile Butadiene Rubber) are used in this model to ensure compatibility with various hydraulic fluids such as HL, HLP, HLPD, HVLP, HVLPD, and HFC. Additionally, the control port X can be either opened or closed depending on the application requirements. The hydraulically active switching prefill valve also includes a check valve feature for the flange connection. One of its notable capabilities is reduced switching noises thanks to end position cushioning effective on both sides of the valve. This design element not only minimizes operational noise but also contributes to optimized switching time characteristics, enhancing overall performance and reliability in demanding applications.

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.
