  • 3FREEZ 10 B-1X/70L2G24K31A1MM

  • Rexroth

  • 0811403019

  • Direct operated flow control valves NG6 and NG10 with integrated electronics and inductive position transducer

  • Position-controlled, minimum hysteresis < 1%

  • The assignment of the hydraulic ports determines the 3-way function (the residual current flows via port P, 3rd way)

  • Adjustable by means of the position-controlled solenoid position, using the position transducer and the integrated valve electronics

  • For subplate mounting: Porting pattern according to ISO 4401

IP65 (If a suitable and a correctly mounted mating connector are used.)


Proportional flow control valves of type 3FREEZ with position control and integrated electronics are offered in sizes 6 and 10. Operation is effected by means of a proportional solenoid with inductive position transducer. The hysteresis is <1 %. The installed electronics have been calibrated in the plant and allow for short actuating times. Due to the valve housing, the residual flow is guided via port P.
