Festo
538020
Precision pressure regulator MS6-LRP-1/2-D2-A8
The Festo 538020 is a size 6 MS-series pilot-controlled precision diaphragm regulator featuring a rotary knob with detent and an actuator lock. It provides constant output pressure with secondary exhausting across an operating pressure range of 0.1 MPa to 1.4 MPa and a pressure regulation range of 0.05 bar to 0.7 bar, delivering a normal nominal flow rate of 1600 l/min and a secondary venting flow rate of 220 l/min. Designed with a G1/8 pressure gauge setup, a moderate corrosion resistance class of 2, and a product weight of 850 g, it operates with compressed air per ISO 8573-1:2010 [7:4:4] or inert gases 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.
