Festo
572079
Air solenoid valve MHJ9-QS-4-LF
The Festo 572079 is a directly controlled 2/2-way closed monostable industrial component featuring a 9 mm width dimension, a hard sealing principle, and a nominal flow rate of 50 l/min normalized to DIN 1343. Operating on 24V DC within a pressure range of 0.05 MPa to 0.8 MPa (0.5 bar to 8 bar, 7.25 psi to 116 psi), this electrical poppet valve without a return spring utilizes a pneumatic spring reset method and includes a QS-4 pneumatic working port. Designed with an IP40 degree of protection, non-reversible flow direction, and a maximum switching frequency of 500 Hz, it supports any mounting position but must not be operated without flow.

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.
