The Bosch Rexroth LC40DR80E7X/ (R900938019) is a high-performance industrial hydraulic valve designed for reliable pressure reduction to a set value. This hydraulically actuated valve features a spool symbol B A and operates as a pilot-operated spool valve. It is capable of handling a maximum pressure as specified by its product group ID, with the exact number of ports and maximum flow rate determined by its size classification. This LC40DR80E7X/ valve is part of Bosch Rexroth's way cartridge valves for pressure functions, which are pilot-operated valves available in either seat or spool designs. The power section, designed as a cartridge valve, fits into a standardized receiving hole according to DIN ISO and is sealed with a control cover. Equipped with pilot control valves for manual or electrically proportional pressure adjustments, these can be integrated into or mounted on the control cover following DIN specifications. By combining these cartridge valves with different control covers, various pressure functions can be achieved. Specifically, this model features a pressure reducing function where the rest position remains open. The design ensures that there is no area difference at port B, meaning no effective areas are present at this port. The same types of cover used for the pressure relief function are applicable here. The operational mechanics involve directing the effective pressure at port A through the pilot oil supply orifice to the spring side of the spool. Below the performance limit and predetermined pressure set at the pilot control valve, the spool maintains an open position due to spring force allowing free flow from port B to port A. Upon reaching the set pressure, the spool closes to reduce the pressure at port A according to its characteristics. The type of connection for this valve is a cartridge valve with an ISO connection diagram. It also specifies an NBR seal type and is compatible with various hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, and HFC. The weight of this model has been determined by its specific design parameters. In summary, Bosch Rexroth's LC40DR80E7X/ (R900938019) hydraulic valve offers robust performance for applications requiring precise pressure reduction capabilities within hydraulic systems.
