Festo
546166
Air solenoid valve VZWM-L-M22C-G1-F5-R1
The Festo part number 546166 is a servo-controlled diaphragm valve featuring a soft sealing principle and a 25 mm nominal width in a 2/2-way, closed, monostable configuration with non-reversible flow direction. This electrical component utilizes an in-line installation design with a G1 fitting connection and accepts a solenoid coil type MH-... available as an accessory. It operates with compressed air as per ISO 8573-1:2010 [7:4:4], inert gas, water, and neutral liquids, supporting liquid media pressures from 0.05 MPa to 0.6 MPa and gaseous media pressures from 0.05 MPa to 1 MPa.

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.
