Festo
577287
Air solenoid valve VSNC-F-B52-D-N14-FN-1A1-EX4-A
The Festo 577287 is a 32 mm wide 5/2-way bistable industrial component featuring an electrical actuation type and a piston gate valve structural design with a soft sealing principle. This 24V DC unit delivers a normal nominal flow rate of 1350 l/min through a NAMUR connection pattern pneumatic working port and operates within a pressure range of 0.15 MPa to 0.8 MPa (1.5 bar to 8 bar) with an adjustable exhaust air function. Certified with IEC-EX EPL Db and Ga, ATEX categories II 2G and II 2D, and DNVGL-TAA000011J, it provides IP65 protection via a plug socket across an explosive ambient temperature range of -40°C to +50°C in accordance with VDI/VDE 3845 (NAMUR) standards and any mounting position.
