Festo Series MS Pressure Regulator, 0.50 to 12 bar Pressure Setting Range, G3/8in Port Size - MS6-LR-3/8-D7-VS, Numeric Part Number: 8232991

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.

Features and Benefits:

• 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

Applications

• 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

What media can be regulated with this device?

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

How does the regulator behave under return flow?

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

What are the environmental limits for storage and operation?

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

Which materials are used for Seals and diaphragm?

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

What is the unit mass and mounting approach?

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