8203861

Precision pressure regulator MS6-LRP-1/2-PE10-VS

The Festo 8203861 is a Size 6 industrial component from the MS series featuring a pilot-controlled piston structural design with constant output pressure and secondary exhausting functions. Operating on a nominal 24 V DC voltage with an analog input signal range of 0 to 10 V, this unit handles an operating pressure of 3.5 bar to 11 bar and a normal nominal flow rate of 9000 l/min. It is designed for compressed air according to ISO 8573-1:2010 [7:4:4] or inert gases, achieving a pressure regulation range of 0.1 bar to 10 bar with a maximum pressure hysteresis of 0.05 bar and moderate corrosion resistance class (CRC) 2.

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.

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.
