The Bosch Rexroth LFA25DBWD2-7X/200 (R900942897) is a high-quality hydraulic control valve designed for subplate mounting with a manual pressure adjustment feature. This valve is part of Bosch Rexroth's product group and is specifically built to provide reliable pressure limiting when paired with a way cartridge valve according to the hydraulic symbol. The hexagon-shaped control cover conforms to ISO standards for way cartridge valves, ensuring compatibility and ease of integration into various hydraulic systems. This model has a pressure rating of up to 350 bar and can handle maximum pressures effectively, making it suitable for rigorous applications that demand precise pressure control. The valve's size 25 configuration allows for manual actuation, offering users direct control over the pressure settings. Its construction includes NBR seals which are compatible with a range of hydraulic fluids such as HL, HLP, HLPD, HVLP, HVLPD, and HFC. The LFA25DBWD2-7X/200 valve operates by utilizing pilot-operated seat or spool design cartridges that are installed into standardized receiving holes according to DIN ISO norms. It features different pressure functions including pressure relief and reducing functions. For the pressure relief function, the seat valve does not have an area difference at port B, meaning no effective area at this port. The pilot oil supply orifice directs effective pressure from port A to the spring side of the element which keeps the spool closed under set pressures until the setpoint is reached. For the pressure reducing function, it operates as a spool valve also without an area difference at port B. This allows free flow from port B to port A until the set pressure is reached, after which the spool closes to reduce pressure according to characteristic curves. Overall, this Bosch Rexroth hydraulic control valve is designed for flexibility in application with its combinable cartridge valves and control covers that enable different pressure functions tailored to specific system requirements.
