The Bosch Rexroth LFA 40 DBS2-7X/315/12 (R978011741) is a sophisticated way cartridge valve designed for pressure functions in hydraulic systems. This pilot-operated valve, available in both seat and spool designs, is engineered to fit standardized receiving holes according to DIN ISO specifications and is securely closed with a control cover. The integrated pilot control valve allows for either manual or electrically proportional pressure adjustment, adhering to mounting dimensions set by DIN standards. This versatile component can be used to achieve various pressure functions by combining it with different control covers. Specifically, the pressure relief function of the LFA 40 DBS2-7X/315/12 employs a seat valve configuration without an area difference at port B, ensuring that the effective pressure at port A is managed via a pilot oil supply orifice to the spring side of the element. The spool remains closed under spring force until the set pressure is reached, upon which it opens to limit the pressure according to predefined characteristics. For pressure reducing functions, this model operates as a spool valve and maintains an open rest position. Similar cover types as those used for the pressure relief function are applicable here. The spool remains open under spring force allowing free flow from port B to port A until reaching the set performance limit and pressure, at which point it closes to reduce the output pressure. The LFA 40 DBS2-7X/315/12 offers flexibility with options for manual pressure adjustment and compatibility with directional valves in various positions (Position a and b), providing unloading capabilities and circulation circuit options where required. It operates within Component series X and X, sustaining maximum operating pressures up to bar, making it suitable for high-demand hydraulic applications that require precise control over pressure regulation or reduction.
