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 < 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 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. The hysteresis is <1 %. The valve amplifier electronics are available as Euro card Due to the valve housing, the residual flow is guided via port P.
