The Bosch Rexroth LFA40DB3-7X/200V/12 (R901428447) is a sophisticated cartridge valve designed for precise pressure control in hydraulic systems. This model, tailored to fit standardized receiving holes according to DIN ISO norms, ensures seamless integration into various hydraulic circuits. The LFA40DB3-7X/200V/12 is engineered as a seat valve without an area difference at port B, which means there's no effective area at this port, ensuring reliable and consistent performance. The valve's pressure relief function operates by directing the effective pressure at port A through the pilot oil supply orifice to the spring side of the element. The spool remains closed under spring force until the set pressure is reached, at which point it opens to limit the pressure at port A according to specific characteristics. This feature is crucial for protecting hydraulic systems from overpressure scenarios. For applications requiring pressure reduction, this valve functions effectively with a rest position that's open. It utilizes a spool valve design also without an area difference at port B. The pilot control valve maintains the spool in an open position under set pressures, allowing free flow from port B to port A until reaching the performance limit. Once this set pressure is achieved, the spool closes to reduce pressure at port A as needed. This model accommodates manual pressure adjustment and can be equipped with various pilot control valves for different applications. It does not include a directional valve but remains versatile for numerous configurations within hydraulic systems. The Bosch Rexroth LFA40DB3-7X/200V/12 offers reliability and adaptability for engineers and technicians looking for precise control in their hydraulic equipment without the need for electrical proportional adjustments.
