Description
- Size 6, 10
- Component series 1X
- Max. operating pressure 250 bar
Features
- 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
Product description
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.
