Festo
577277
Air solenoid valve VSNC-FTC-M52-MD-G14-FN
The Festo part number 577277 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. It delivers a normal nominal flow rate of 800 l/min according to DIN 1343 across an operating pressure range of 0.25 MPa to 0.8 MPa (2.5 bar to 8 bar) utilizing a soft sealing principle and a negative overlap lap. This pilotted electrical actuator conforms to VDI/VDE 3845 (NAMUR) standards with a NAMUR connection pattern, adjustable exhaust air function, mechanical spring reset method, detenting and non-detenting manual override, and DNVGL-TAA000011J certification. Operating voltage is supplied via a solenoid coil ordered separately, and signal status display is available with accessories for mounting in any position with a non-reversible flow direction.
