Festo
4451
Hand slide valve W-3-M5
The Festo part number 4451 is a 3/2 bistable manual industrial component featuring a direct sleeve slide design structure with a soft sealing principle and M5 pneumatic connections. Constructed with a brass housing, anodized wrought aluminum alloy screw-in stud, and a nominal size of 2.5 mm, this direct-actuated valve operates within a working pressure range of -0.95 to 8 bar and handles a standard nominal flow rate of 120 l/min using compressed air conforming to ISO8573-1:2010 [7:4:4]. It supports reversible flow direction, any assembly position, and an ambient or medium temperature range of -10 to 60 °C with an actuating force of 10 N and a product weight of 25 g, allowing lubricated operation that is subsequently required for further operation.
