173404
Solenoid valve MEH-5/2-1/8-P-I-B
The Festo 173404 is an electrical 5/2 monostable industrial component featuring a piston slide design structure with a 17.8 mm width, an 18 mm grid dimension, and a 5 mm nominal size. This piloted valve operates within a working pressure range of 3 to 8 bar and a pilot pressure of 2.5 to 8 bar, delivering a standard nominal flow rate of 600 l/min through a soft sealing principle and throttleable exhaust-air function. Incorporating internal pilot air supply, positive overlap, a mechanical spring reset, and an IP65 protection class, the unit holds c UL us - Recognized (OL) authorization and permits assembly in any position with detenting manual override accessories.

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.
