Festo
19789
Air solenoid valve JMFH-5-1/4-B
The Festo 19789 is an electrical 5/2-way bistable piston gate valve featuring a 32 mm width, a 10 mm nominal width, and a G1/4 pneumatic working port with internal pilot air supply. This piloted component delivers a normal nominal flow rate of 1600 l/min across an operating pressure range of 0.2 MPa to 1 MPa (2 bar to 10 bar) at a maximum switching frequency of 3 Hz. Built with a soft sealing principle, positive overlap, and non-detenting manual override, the unit includes an adjustable exhaust air function and supports any mounting position.

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.
