Festo
170331
Air solenoid valve CPE18-M3H-5/3G-QS-10
The Festo 170331 is an 18 mm wide electrical 5/3-way closed piston gate valve featuring an 8 mm nominal width and a normal nominal flow rate of 1050 l/min normalized to DIN 1343. Operating on 230V AC within a pressure range of 0.25 MPa to 1 MPa (2.5 bar to 10 bar), this component utilizes a soft sealing principle, a mechanical spring reset method, and an adjustable exhaust air function with QS-10 pneumatic working ports. It provides IP65 protection with a plug socket, features detenting via accessory and non-detenting manual override, and carries c UL us recognition, DNV and UL certificate issuing authorities, along with CE and UKCA markings.

Request a QuoteWhy no listed price?
Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Festo references — within one business day.
