Festo 1/4 in G Regulator - 14 bar, MS4-LR-1/4-D7-VS-DM1 800L/min MS

This regulator controls and stabilises compressed Air pressure for industrial pneumatic systems. It is a compact, metal-bodied pressure control unit designed for integration into automation and mechanical assemblies where consistent downstream pressure and regulated Airflow are required.

• Die-cast aluminium body offers corrosion resistance and durability
• Maximum flow capacity 800 L/min supports high-demand pneumatic circuits
• Rated to 14 bar for robust pressure management in industrial settings
• Port size 1/4in G enables standardised connection to G‑threaded fittings
• Operating temperature range -10 to 60°C allows use in varied environments
• Conforms to ISO 8573-1:2010 (7:4:4) for particle, water and oil purity control

• Suitable for control panels in factory automation systems
• Ideal for feeding pneumatic actuators and valves in assembly lines
• Used with Air preparation units in electronics manufacturing
• Can be used for pressure regulation in test rigs and test benches
• Suitable for incorporation into maintenance and repAir stations

The unit meets RoHS requirements and complies with ISO 8573-1:2010 class 7:4:4 and VDMA24364-B1/B2-L, addressing materials and Air quality parameters.

The device provides a G‑threaded connection with a 1/4in G port for compatibility with common pneumatic fittings.

It is rated to operate between -10 and 60°C, maintaining control functionality across that temperature span.

Designers can plan for up to 800 L/min flow and a maximum operating pressure of 14 bar when specifying supply and downstream components.
