Festo 1/4 in G Regulator - 14 bar, MS4-LR-1/4-D6 1800L/min, G MS

This regulator controls and stabilises pneumatic supply pressure for industrial equipment, providing reliable Air pressure management in automated and mechanical systems. Designed for installations requiring a compact, threaded port connection, it is suited to environments where controlled flow and durability are required without extensive thermal extremes.

• Die-cast aluminium construction reduces component weight and resists mechanical wear
• 1800 L/min maximum flow supports high-volume pneumatic demand
• 14 bar maximum operating pressure enables heavy-duty system control
• Operates from -10°C to 60°C for varied indoor industrial conditions
• G-thread 1/4 in port simplifies connection to standard pneumatic fittings
• Conforms to specified particulate and oil classes to maintain Air quality

• Suitable for Air preparation units in factory automation lines
• Ideal for pressure control in pneumatic actuators and valves
• Used with compressed-Air distribution manifolds in workshops
• Can be used for supply regulation to assembly-line tools
• Suitable for retrofitting industrial control panels requiring threaded connections

It meets ISO 8573-1:2010 particulate and oil classification requirements specified for compressed-air purity.

It adheres to VDMA24364-B1/B2-L guidelines for relevant mechanical and pneumatic interfaces.

The unit is RoHS certified, restricting certain hazardous substances in its materials.

When replacing a unit, match the G-thread 1/4 in port and ensure the new component supports up to 14 bar and a similar flow capacity.
