Festo
559723
One-way flow control valve VFOC-S-S4-Q4
The Festo 559723 is a manual one-way flow control valve function designed for supply air featuring a slotted head screw adjusting element and two push-in sleeves for QS-4 pneumatic connections compatible exclusively with Festo QS fittings. This component operates across a working pressure range of 0.2 to 10 bar, an ambient and medium temperature range of -10 to 60 °C, and utilizes compressed air conforming to ISO8573-1:2010 [7:4:4] with a product weight of 9.2 g. It delivers a standard nominal flow rate of 0 to 100 l/min in the flow control direction and 60 to 100 l/min in the non-return direction, while meeting RoHS and VDMA24364-B2-L PWIS conformity standards.
