Festo
The Festo part number 6308 is an industrial one-way flow control valve featuring internal thread G3/8 pneumatic connections on both ports and a brass knurled screw adjusting element. Housed in die-cast zinc with a product weight of 225 g, this RoHS compliant component supports front panel mounting or through-hole installation in any mounting position. It operates within a pressure range of 0.01 MPa to 1 MPa (0.1 bar to 10 bar, 1.45 psi to 145 psi) and handles compressed air according to ISO 8573-1:2010 [7:4:4] at ambient and medium temperatures from -20 °C to 75 °C. The unit delivers a standard nominal flow rate of 1010 l/min in the flow control direction and 1150 l/min in the non-return direction, provides ATEX explosion protection for zones 1, 2, 21, and 22, and permits oil-lubricated operation.
