Festo
The Festo 534343 is an industrial component featuring a one-way flow control function with a QS-10 pneumatic connection 1 and a G3/8 pneumatic connection 2. It utilizes a knurled screw adjusting element for screw-in mounting with an external thread, operating within a pressure range of 0.2 bar to 10 bar and temperatures from -10 °C to 60 °C. The unit delivers a standard nominal flow rate of 900 l/min in the flow control direction and 540 l/min to 975 l/min in the non-return direction using compressed air as per ISO 8573-1:2010 [7:4:4].
