MS Series – Pressure Regulators

Festo MS Series – Pressure Regulators

The Festo MS Series pressure regulators are engineered to deliver highly stable and accurate pressure control for compressed-air systems used across all automation environments. Designed with modularity and ISO compatibility in mind, these regulators ensure reliable downstream air supply, protecting components and improving the efficiency and lifespan of pneumatic equipment.

Available in multiple sizes, flow capacities, and adjustment ranges, the MS Series fits seamlessly into air preparation assemblies and offers a wide selection of functional variants for precise control of outlet pressure.

⭐ Important: The MS Series provides exceptional pressure stability, wide configurability, and modular integration—making it the preferred solution for modern industrial air preparation systems.

Design & Functionality

MS Series regulators operate by reducing fluctuating upstream pressure into a stable, controlled outlet pressure. Their internal control diaphragm and precision spring assembly ensure accurate regulation across varying loads and flow demands.

Festo offers several types of MS regulators, including:
• Direct-operated pressure regulators
• Diaphragm regulators with relieving function
• Precision regulators for high-accuracy applications
• Modular units with gauge connection and lockable adjustment

The series is engineered for low hysteresis, quick pressure response, and high flow consistency, ensuring stable pneumatic performance even in dynamic automation environments.

⭐ Important: The MS modular design ensures compatibility with filters, lubricators, soft-start valves, and safety components—allowing easy configuration of complete air preparation systems.

Total Crossed Beams

(Applied to the functional coverage of regulator variants)

Comprehensive pressure regulation capabilities spanning standard, high-precision, relieving, and non-relieving options.
