Specifications
Supplier part number: Rexroth - BOSCH - LFA_16_DB3-7X-200
Name:Logic Elements (Rexroth - BOSCH). - Pressure Relief Function , Control Cover. - Type : LFA. - Nominal Size NS 16. - DB : With Manual Pressure Adjustment.
Description:The Bosch Rexroth LFA control cover with the DB designation is designed for the pressure relief function in hydraulic systems with 2-way cartridge valves . 🔧 Function and Design The LFA control cover works with a cartridge valve to limit the system pressure . The key elements of its operation include: How it Works: The pressure at port A is routed through a pilot oil orifice to the spring side of the valve spool . The manual adjustment sets the spring force, which determines the pressure at which the valve will open . Pressure Limitation: Once the pressure at port A reaches the set level, it overcomes the spring force and opens the spool, limiting the pressure according to the valve's flow characteristics . 📋 Key Technical Specifications Specification Detail Type LFA Function Pressure Relief (DB) Nominal Size (NS) 16 Adjustment Manual pressure adjustment Max. Operating Pressure Up to 420 bar Mounting Standard DIN ISO 7368 Design Pilot-operated seat valve This control cover is typically used with a compatible LC type cartridge valve (e.g., LC..DB...) to complete the pressure relief function . If you need information on a specific variant or a compatible cartridge valve, please let me know.
