LFA32DB1-7X/420/12

The LFA32DB1-7X/420/12 control cover belongs to the LFA 2 Way Control Covers series from Bosch Rexroth and provides directional flow management in hydraulic automation assemblies where modular stack valves share a manifold. A nominal size of 32 matches circuit sections that need large passage areas to minimize pressure loss, while a maximum operating pressure of 420 bar allows reliable service in high-pressure installations. External connections are provided as SAE threads under the /12 option so technicians can attach standardized tube fittings without adapters. Mounting is completed with UNC bolts also denoted by the /12 suffix, giving hardware continuity in North American frames. The cover is designed for HL or HLP hydraulic fluids specified in DIN 51524, ensuring compatibility with common mineral oil power units.

Permissible fluid temperature spans –20 °C to +80 °C so the cover endures cold starts and elevated oil temperatures during sustained duty. A viscosity range of 2.8 to 500 mm²/s lets the unit accommodate thin start-up oils and thicker lubricants that appear under heavy load. System cleanliness must reach ISO 4406 (c) 20/18/15 to limit abrasive particles that could damage sealing edges and throttling lands. The design omits a remote control port because it is supplied as Type D without the /F feature, simplifying installation when external pilot signals are not required for the application.
