Festo
170329
Air solenoid valve CPE18-M3H-5/3B-QS-8
The Festo 170329 is an electrical 5/3-way pressurized industrial component featuring a piston gate valve structural design with an 18 mm width and an 8 mm nominal width. This unit delivers a normal nominal flow rate of 780 l/min through QS-8 pneumatic working ports at an operating pressure range of 0.25 MPa to 1 MPa (2.5 bar to 10 bar) and operates on 230V AC. Constructed with a soft sealing principle, mechanical spring reset, and adjustable exhaust air function, the device offers IP65 protection with a plug socket and supports both detenting via accessory and non-detenting manual override. Certified by c UL us and DNV with CE and UKCA markings, the assembly accommodates any mounting position.
