The Bosch Rexroth LFA32DBU3D2-126-7X/420A000B200 (R901081985) is a sophisticated way cartridge valve designed for pressure functions, including both pressure relief and pressure reducing capabilities. This pilot-operated valve can be utilized in seat or spool designs and is intended for integration into a standardized receiving hole according to DIN ISO norms, secured with a control cover. The model features an integrated pilot control valve for manual or electrically proportional pressure adjustments, which can be mounted directly on the control cover. The flexibility of combining this cartridge valve with various control covers allows for the realization of different pressure functions tailored to specific applications. For the pressure relief function, the valve operates as a seat valve without an area difference at port B, meaning there is no effective area at this port. The effective pressure at port A is directed through the pilot oil supply orifice to the spring side of the element. When the set pressure is reached, as determined by the pilot control valve, the spool opens to limit the pressure at port A according to its characteristics. In terms of pressure reducing function, this model has a rest position that remains open. Similar to its operation in pressure relief mode, but designed as a spool valve without an area difference at port B, it allows free flow from port B to port A until reaching the set pressure whereupon it closes to reduce the pressure at port A. The LFA32DBU3D2-126-7X/420A000B200 offers versatility with its different positions for manual adjustment and compatibility with directional valves such as WEH..., WEE..., and WED... series for various DB functions. Additionally, it provides options for circulation circuit configurations—either open or blocked—ensuring that users can tailor their hydraulic systems precisely to their requirements while maintaining efficient and reliable operation across diverse applications.
