Description
- Size 6, 10
- Component series 1X
- Max. operating pressure 250 bar
Features
- Direct operated flow control valves NG6 and NG10
- The assignment of the hydraulic ports determines the 2-way or 3-way function (the residual current flows via port P, 3rd way), symbol “NO” (normally open) can only be realized as 2-way function
- Adjustable by means of the solenoid current
- For subplate mounting: Porting pattern according to ISO 4401
Product description
Proportional flow control valves of type 3(2)FREX without position control are offered in sizes 6 and 10. Operation is effected by means of proportional solenoid. The hysteresis is < 5 %. The valve amplifier electronics are available in different designs. The “NO” (normally open) symbol can only be used as 2-way flow control valve (type 2FREX). The “NC” (normally closed” symbol can be used as 3-way or 2-way flow control valve. Due to the valve housing, the residual flow in the 3-way version is guided via port P. For the 2-way version, the following is true: A to B (P and T are closed).
