Festo
538014
Precision pressure regulator MS6-LRP-3/8-D4-A8
The Festo 538014 is a pilot-controlled precision diaphragm regulator of the MS series, size 6, featuring a rotary knob with detent for actuator locking and a pressure regulation range of 0.05 bar to 2.5 bar. This component supports an operating pressure from 1 bar to 14 bar, a normal nominal flow rate of 1400 l/min, and a secondary venting flow rate of 450 l/min while utilizing compressed air per ISO 8573-1:2010 [7:4:4] or inert gases. Weighing 850 g with a CRC rating of 2 for moderate corrosion stress, it is designed for any mounting position and operates across 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.
