Festo G3/8 in Pressure Regulator - 2 Mpa 4500L/min, G MS

This pressure regulator provides stable outlet pressure control for compressed Air and inert gases in pneumatic systems. Designed for direct diaphragm actuation with secondary exhausting and return-flow capability, it maintains a constant downstream pressure across varying loads. The unit accepts G‑threaded connections and includes a 3/8in gauge port for pressure monitoring, operating over a wide ambient and media temperature band suitable for typical industrial environments.

• 0.5 to 12 bar selectable range for precise pressure adjustment
• 4500 L/min nominal flow for high-throughput pneumatic circuits
• 2 MPa maximum operating pressure for high-pressure applications
• Die-cast aluminium housing for reduced component mass
• Rotary knob with detent for secure repeatable setpoints

• Suitable for large-volume pneumatic actuation systems
• Used with compressed Air meeting ISO 8573-1:2010 purity classes
• Ideal for control panels requiring Compact pressure regulation
• Used for inert gas pressure conditioning in production lines
• Suitable for installations needing a G‑threaded pressure regulator port

It handles compressed Air to ISO 8573-1:2010 [7:4:4] and inert gases, and permits lubricated operation when lubrication is used.

It includes a return-flow function and secondary exhausting to manage backflow and venting during pressure transitions.

Storage, ambient and media temperatures range from -10°C to 60°C.

Seals and membrane are manufactured from NBR to suit standard pneumatic media.

The device weighs 730 g and is intended to be mounted using supplied accessories.
