Description Size 6, 10 Component series 1X Max. operating pressure 250 bar Features Direct operated flow control valves NG6 and NG10 Position-controlled, minimum hysteresis 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 external valve electronics For subplate mounting: Porting pattern according to ISO 4401 Product description Proportional flow control valves of type 3FREEZ with position control are offered in sizes 6 and 10. Operation is effected by means of a proportional solenoid with inductive position transducer.
