Logic Elements (Rexroth - BOSCH). - Pressure Relief Function , Control Cover. - Type : LFA.

The LFA..DBE control cover from Bosch Rexroth is designed for logic cartridge valves and provides an electro-proportional pressure adjustment function . This variant is used without a cartridge and without electrical feedback, meaning the proportional solenoid adjusts the pilot pressure based on the electrical input signal, but the valve does not send a position signal back to the controller .📋 Key Technical SpecificationsHere is a summary of the specifications for your valve:Specification DetailType LFA (Control Cover) Function Pressure Relief (DBE) Nominal Size (NS) 16 Adjustment Electro-proportional (DBE) Max. Operating Pressure Up to 350 / 420 bar (depending on variant) Mounting Standard DIN ISO 7368 Seals NBR (standard) or FKM (optional)

The Bosch Rexroth LFA..DBEM control cover is designed for the pressure relief function and features electro-proportional pressure adjustment with a manual maximum pressure relief function, without electrical feedback.Here are the key specifications and an overview of its design.📋 Technical Specifications (NS 16)Specification DetailType LFA..DBEM (Control Cover)Function Pressure ReliefNominal Size (NS) 16Adjustment Electro-proportional (DBE) with additional manual maximum pressure reliefMax. Operating Pressure Up to 420 barMounting Standard DIN ISO 7368Electrical Feedback Without (Open-loop control)🔧 Design and FunctionPilot-Operated Control: This is a pilot-operated valve. The power section (a 2-way cartridge valve) fits into a standardized receiving hole and is closed with the LFA control cover.Pressure Adjustment: The DBE designation indicates electro-proportional pressure adjustment via an attached pilot control valve (such as the DBET series). The additional "M" in the designation indicates that a manual maximum pressure relief function is also integrated for an extra layer of safety or override capability.Operation: In the pressure relief function, pressure at port A acts on the spring side of the valve spool. When the pressure reaches the set electro-proportional value, the spool opens, limiting the pressure at port A according to the pressure-flow characteristics.Safety Feature: The manual adjustment allows the maximum system pressure to be capped and set independently, which can serve as a safety backup for the electronic control.Seals: Available with NBR (standard) or FKM (optional) seals.If you need details on the compatible LC cartridge valve or the pilot control valve (DBET series) for this cover, please let me know.

The Bosch Rexroth LFA..DBW logic control cover is designed for the pressure relief function, using an integrated pilot control valve for electrical unloading. The designation "W" signifies it is prepared for the mounting of a directional valve, typically a WE6 type, to perform the unloading function, as indicated by the code "DBW" in the type key.🔧 Function and DesignFunction: This is a pilot-operated pressure relief valve. Pressure at port A acts on the spring side of the spool. When the set pressure is reached, the spool opens to limit the pressure at port A.Unloading Circuit: The core function is the unloading circuit. By mounting a directional valve (e.g., 3WE6 or 4WE6) onto the cover, the system pressure can be unloaded electrically. In its de-energized position, the directional valve connects the spring chamber to the tank, causing the system pressure to drop to a low level and the flow to circulate with minimal pressure.Design: It is a pilot-operated 2-way cartridge valve (power section) combined with a control cover that houses the pilot valve and necessary orifices.📋 Key Technical Specifications (NS 16)The LFA..DBW control covers are available for NS16 and larger sizes.Specification DetailType LFA..DBW (Control Cover)Function Pressure Relief with Electrical Unloading CircuitNominal Size 16Mounting Standard DIN ISO 7368Max.

🔧 Function and Design: LFA..DBWD for Isolation FunctionsBased on the available information, the LFA..DBWD control cover from Bosch Rexroth is a pilot-operated logic element designed primarily for pressure relief and pressure reducing functions. The "D" in DBWD indicates a manual adjustment for pressure setting, and the "W" designates an electric unloading circuit for mounting a directional valve.Your query specifies "For Isolation Functions." This can be achieved through the DBWD's "DB function" which, with a specific directional valve, can hydraulically block the cartridge valve, isolating port A from port B. The Bosch Rexroth documentation confirms this "Blocking function" for the DBWD when used with directional valves like the 3WE6A... or 4WE6M.. types, making it suitable for isolation duties.📋 Key Technical Specifications (NS 16)Based on the product data, the specifications for your valve are:Specification DetailType LFA..DBWD (Control Cover)Function Pressure Relief / Reducing with Electric Unloading CircuitNominal Size 16Mounting Standard DIN ISO 7368Max.
