Festo
161731
Air solenoid valve MN1H-2-3/4-MS
The Festo 161731 is an electrically actuated diaphragm valve featuring a 2/2-way, closed, monostable function with a 20 mm nominal width and G3/4 in-line fitting connection. Designed with a soft sealing principle and piloted control, it operates with filtered compressed air using a 200 µm filter mesh across a medium pressure range of 0.5 bar to 10 bar. The component supports multiple coil characteristics including 110 V AC, 230 V AC, and 24 V DC, and accommodates an ambient and medium temperature range of -10 °C to 60 °C with optional oil lubrication.

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.
