Festo
538031
Precision pressure regulator MS6N-LRP-1/4-D4-A8
The Festo 538031 is an MS-series size 6 industrial component featuring a pilot-controlled precision diaphragm regulator with a rotary knob with detent for actuator locking. It delivers a constant output pressure with secondary exhausting, providing a normal nominal flow rate of 1100 l/min and a secondary venting flow rate of 450 l/min across an operating pressure range of 1 bar to 14 bar and a regulation range of 0.05 bar to 2.5 bar. Designed for any mounting position using compressed air or inert gases, this unit weighs 850 g and operates within a temperature range of -10 °C to 60 °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.
