Precision pressure regulator MS6-LRP-1/2-D4-A8-Z

The Festo 538023 is a size 6 MS-series pilot-controlled precision diaphragm regulator featuring a rotary knob with detent and a constant output pressure function with secondary exhausting. It operates within an input pressure range of 1 bar to 14 bar, offers a pressure regulation range of 0.05 bar to 2.5 bar with a maximum pressure hysteresis of 0.02 bar, and delivers a normal nominal flow rate of 2300 l/min alongside a secondary venting flow rate of 450 l/min using compressed air or inert gases. Constructed for any mounting position with a product weight of 850 g and moderate corrosion resistance class 2, this unit accommodates operating, medium, and ambient temperatures from -10 °C to 60 °C and includes setup for a G1/8 pressure gauge.

Why 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.

Engineering context

Identification and RFQ Guidance

Confirm the exact configuration

Use the manufacturer part number and model code—not appearance alone. Connection, size, material, voltage, pressure, seal, and control options can differ within the same product family.

What to include in your RFQ

Provide quantity, delivery country and ZIP/postal code, required condition, target date, and photographs of the existing nameplate when available.
