Festo
The Festo 8040566 is a direct-controlled electrical industrial component featuring a 3/2-way, closed, monostable valve function with a 15 mm width and a normal nominal flow rate of 13.5 l/min. Built to conform to ISO 15218 standards with a size 15 mm sub-base pneumatic working port, this part operates on 24V AC within an operating pressure range of 0.15 MPa to 0.8 MPa (1.5 bar to 8 bar | 21.75 psi to 116 psi). It utilizes a soft sealing principle, mechanical spring reset, non-detenting manual override, and non-reversible flow direction, providing an IP65 degree of protection, a 100% duty cycle, and flexible mounting in any position.
