Festo
529811
Pressure build-up valve MS6-DE-3/8-V110
The Festo 529811 is an electrically actuated industrial component featuring a piston seat design structure, mechanical spring reset, and internal piloted air supply with a non-reversible flow direction. Engineered with a 2/2 valve function, 110V AC characteristic coil data, and a working pressure of 4 to 18 bar, this unit delivers a standard nominal flow rate of 5,050 l/min at a 100% duty cycle. Operating within a medium temperature range of -10 to 60 °C, it accommodates compressed air conforming to ISO8573-1:2010 [7:4:4] or inert gases, and includes a detenting and pushing manual override with a CRC corrosion resistance classification of 2.

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.
