Festo
542649
Service unit combination MSB6-1/2:J4D7A1-WP
The Festo 542649 is an MS-series size 6 industrial component featuring a design structure combining a start-up valve, on/off valve, and filter regulator with a pressure gauge. It operates within a working pressure of 4.5 to 10 bar, a pressure control range of 4 to 9 bar, and delivers a standard nominal flow rate of 3,000 l/min using compressed air or inert gases. Equipped with a 24V DC 2.5W coil, fully automatic condensate drain, 5 µm filtration grade, plastic bowl guard, and a lockable rotary knob actuator, this unit maintains a constant output pressure with secondary exhaust and return flow in a vertical +/- 5° assembly position.

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.
