Festo
561021
Sub-base VMPAL-AP-20-QS8-1-T1
The Festo part number 561021 is an industrial component featuring a width of 21.2 mm, a length of 107.3 mm, a valve size of 20 mm, and a product weight of 76.88 g. Designed with a reversible flow direction, duct 1 pressure zone separation, and accommodation for one solenoid coil, this unit supports a maximum of one valve position within an interchangeable valve size manifold design. It operates within a pressure range of -0.9 bar to 10 bar and a pilot pressure of 3 bar to 8 bar using compressed air according to ISO 8573-1:2010 [7:4:4], allowing for oil lubrication operation with 8 mm outside diameter pneumatic tubing connections 2 and 4. Built with a corrosion resistance class of 3 and VDMA24364-B1/B2-L LABS conformity, the component functions at ambient temperatures from -5 °C to 50 °C.
