Proportional Directional Valve 4WRGE10V50L-1X/315G24ETK31/C1M - Bosch Rexroth R900967301

A valve block without extra pilot piping is quicker to fit and less prone to leaks. The 4WRGE10V50L-1X coded ETK31 is supplied and drained entirely internally, controls 50 l/min nominal flow and holds up to 315 bar.

Benefits

• Internal pilot oil supply and internal drain leave only the four main ports to pipe.
• 50 l/min nominal flow gives small and medium cylinders a fine resolution.
• Up to 170 l/min maximum flow if more is briefly demanded.
• A ±10 mA command value through on-board electronics on a 24 VDC supply.
• 315 bar operating pressure, 8.63 kg mass, NBR seals for HL hydraulic fluid.

Application

The build suits compact power packs and machine modules that manage without a separate pilot supply. The return must not carry high back pressure, otherwise the version with external drain is the better choice. Spool symbol V blocks in centre.
