Festo
The Festo 8068737 is an industrial component featuring an exhaust air flow control non-return function with a QS-6 pneumatic connection 1 and an R1/4 pneumatic connection 2. This screw-in component utilizes a manual actuation type with a rotary knob featuring a latch, housed in PBT with a 16 mm width across flats and support for any mounting position. It operates within an ambient temperature range of -10 °C to 60 °C and an operating pressure range of 0.02 MPa to 1 MPa, delivering a standard nominal flow rate of 400 l/min in the flow control direction and 350 l/min to 450 l/min in the non-return direction using compressed air as per ISO 8573-1:2010 [7:4:4]. Compliance includes ATEX certification for Zones 1, 2, 21, and 22, along with VDMA24364 Zone III LABS conformity, and permits oil lubrication operation.
