Proportional Directional Valve 4WRDE16V1-150L-6X/VXY/24F1 - Bosch Rexroth R901550234

Spool symbol V1 is what separates this valve from the otherwise identical V version. It meters 150 l/min nominal flow at size 16, accepts the command value as a 4-20 mA current and works with a fully external pilot circuit.

Benefits

• Spool symbol V1, differing from the widespread V version of the same series
• 150 l/min nominal flow against a valve maximum of 460 l/min
• External pilot feed and external return, pilot pressure independent of load pressure up to 350 bar
• 4-20 mA command value, unaffected by cable length and pick-up
• Internal piston position feedback, mass 10 kg, mounting pattern ISO 4401-07-07-0-05

Application

Symbol V1 is specified where the design requires spool behaviour that differs from the V version. When ordering a replacement the symbol therefore has to be matched against the name plate. The external pilot circuit assumes a dedicated pilot oil supply.

Manufacturer
