Festo
8175241
Pressure regulator MS4-LR-1/4-D6-AG-BAR-F1A-B
The Festo Size 4 MS series industrial component (Part Number 8175241) is a directly controlled piston pressure regulator featuring a rotary knob with detent, integrated pressure gauge, and secondary exhausting with a return flow characteristic. It operates within a pressure range of 1 bar to 10 bar and a regulation range of 0.3 bar to 7 bar, delivering a normal nominal flow rate of 1800 l/min using compressed air or inert gases. Certified with a Class 7 cleanroom rating according to ISO 14644-1 and suitability for Li-ion battery production with reduced Cu/Zn/Ni values, this regulator functions in medium and storage temperatures from -5 °C to 50 °C in any mounting position.

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.
