Festo
The Festo 546146 is a servo-controlled diaphragm valve featuring a 2/2-way, closed, monostable valve function with a soft sealing principle and a 13.5 mm nominal width. Designed for in-line installation with a G1/4 fitting connection and an upright preferred mounting position, this electrically actuated component accepts media including compressed air, inert gas, water, and neutral liquids. Gaseous media operate at pressures from 0.05 to 1 MPa, while liquid media function within a 0.05 to 0.6 MPa range, supported by a differential pressure of 0.5 bar and an overload pressure of 4 MPa.

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.
