Pressure regulator MS4-LR-1/4-D6-AG-MPA-F1A-B
The Festo size 4 industrial component from the MS series is a pressure regulator featuring a directly controlled piston design with an integrated pressure gauge and a rotary knob actuator lock with detent. Operating within a pressure range of 1 bar to 10 bar and a regulation range of 0.3 bar to 7 bar, this device delivers a normal nominal flow rate of 1800 l/min using compressed air or inert gases. It provides constant output pressure with secondary exhausting and return flow characteristics, functioning across a medium and storage temperature range of -5 °C to 50 °C.

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.
