Logic Cover LFA80EWA-6X/CB20DQ6G24 - Bosch Rexroth R900972058

A two-way cartridge valve is only as traceable as the feedback on its spool position. The LFA80EWA-6X/CB20DQ6G24 control cover sits on the size 80 cartridge valve, drives it with a 24 VDC solenoid and reports the spool position back. It works up to 420 bar and passes flow rates of up to 6100 l/min.

Benefits

• Spool position monitoring at the cover itself, so the valve state can be evaluated in the plant control
• Flow up to 6100 l/min through size 80, sized for installations with high oil demand
• Operating pressure up to 420 bar with NBR seals and HL hydraulic fluid
• Cavity to ISO 7368, so the cover fits standardised valve bores
• Solenoid control from the usual 24 VDC plant supply
• 27.01 kg cover mass as a planning figure for lifting gear and manifold layout

Application

The cover belongs on manifolds of presses, rolling mills and hydro power plants where size 80 cartridge valves switch the main oil flow. Position feedback is needed wherever a sequence control may only step forward once the valve state has been confirmed.
