Specifications
Supplier part number: Rexroth - BOSCH - LFA_16_DBW3-7X-200
Name:Logic Elements (Rexroth - BOSCH). - Pressure Relief Function , Control Cover. - Type : LFA. - Nominal Size NS 16. - DBW : For Electrical. - Unloading Circuit. - For Mounting A Directional Valve.
Description: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 Design Function: 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 Detail Type LFA..DBW (Control Cover) Function Pressure Relief with Electrical Unloading Circuit Nominal Size 16 Mounting Standard DIN ISO 7368 Max. Operating Pressure 420 bar Pilot Valve Mounting Prepared for mounting a directional valve, e.g., WE6 type
