Festo
8084273
Air solenoid valve MHJ9-QS-4-MF/LP
The Festo 8084273 is a 9 mm wide, directly controlled 2/2-way closed monostable industrial component featuring a hard sealing principle and a poppet valve structural design without a return spring. It operates at 24V DC with an operating pressure range of 0.05 MPa to 0.4 MPa (0.5 bar to 4 bar / 7.25 psi to 58 psi), delivering a normal nominal flow rate of 100 l/min and a maximum switching frequency of 1000 Hz. This non-reversible component utilizes a pneumatic spring reset method, incorporates QS-4 pneumatic working ports, provides an IP40 degree of protection, and is rated for block assembly with flow at a maximum ambient temperature of 45 °C without operating 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.
