The Bosch Rexroth SF 150 A1-1-4X//12 (R900565892) is a high-quality pilot-operated check valve designed for tank installations and features a flange connection suitable for various hydraulic applications. This model is part of the SF series, known for its robust construction and reliable performance in controlling the flow of hydraulic fluid within a system. The valve is equipped with a housing that includes a low-pressure flange, which can be continuously rotated to facilitate easy installation and alignment within the hydraulic circuit. It also comes with a nameplate for easy identification.
Additionally, the SF 150 A1-1-4X//12 features a control cylinder that manages the opening and closing of the valve, ensuring fluid flows in one direction while preventing backflow. Connection ports X and Y can be outfitted with connection flanges upon request, providing flexibility in system integration. The mounting screws included with this model allow for secure attachment to various surfaces or components.
This particular model does not include an inductive position switch but is available in version QGZ, which indicates specific design characteristics such as predecompression options that can reduce switching noises through damping measures. The rotatable low-pressure connection housing adds to the ease of use by allowing adjustments to be made post-installation without compromising system integrity.
The Bosch Rexroth SF 150 A1-1-4X//12 valve supports high operating pressures and flow rates, making it suitable for demanding industrial applications requiring precise control over hydraulic fluid movement. Its design ensures reliable operation and longevity, even under rigorous conditions. This check valve represents Bosch Rexroth's commitment to engineering excellence and innovation in hydraulic components.
