Proportional Directional Valve 4WRDE10V50L-6X/VPY/24A5 - Bosch Rexroth R901503478

An internal pilot feed saves the dedicated pilot pump, an external Y return protects pilot control from back pressure in the tank. This size 10 version combines both advantages at 50 l/min nominal flow and a mass of only 7.5 kg.

Benefits

• Internal pilot feed, so no separate pilot oil supply is required
• External pilot return through Y, independent of pressure in the collecting tank line
• 50 l/min nominal flow, valve maximum 170 l/min, operating pressure up to 350 bar
• Internal piston position feedback, spool symbol V, command value ±10 V
• Mass 7.5 kg, FKM seals, mounting pattern ISO 4401-05-05-0-05

Application

This configuration suits power units without their own pilot pump whose return line is nevertheless loaded by a cooler or filter. The separate Y outlet bypasses that pressure loss completely. The subplate has to carry the Y port open and pressureless to tank.
