Festo
The Festo part number 577279 is a 32 mm wide industrial component featuring a switchable 5/2- or 3/2-way valve function with a plate seat structural design and internal pilot air supply port. Operating at a pressure range of 0.25 MPa to 0.8 MPa (2.5 bar to 8 bar), this piloted unit delivers a normal nominal flow rate of 800 l/min and incorporates a NAMUR pneumatic working port conforming to the VDI/VDE 3845 standard. It utilizes a soft sealing principle, mechanical spring reset, adjustable exhaust air function, and a detenting or non-detenting manual override, while requiring a separately ordered solenoid coil for electrical actuation and holding DNVGL-TAA000011J certification.
