Festo
The Festo 546828 is a 42 mm wide industrial component engineered for pneumatic vertical stacking as a pressure regulator for two reversible functions, operating on compressed air according to ISO 8573-1:2010 [7:4:4]. Built to ISO 5599-1 norms, this unit provides constant output pressure with secondary exhausting across a regulation range of 0.05 MPa to 1 MPa (0.5 bar to 10 bar, 7.25 psi to 145 psi) and features an IP65 and NEMA 4 degree of protection. Weighing 640 g with a CRC of 0 and VDMA24364-B1/B2-L LABS conformity, it mounts in any position on a manifold or individual sub-base with inlet pressures spanning 0.05 MPa to 1 MPa and allows optional pressure gauge integration.
