FESTO MS-DL Series Pneumatic Soft-Start Valves

Controlled Pressure-Up with Built-In Safety

The Festo MS-DL Series Soft-Start Valves are engineered to safely and efficiently pressurize pneumatic systems during startup. Integrated into the renowned MS series of air preparation units, these soft-start valves provide a gradual build-up of pressure to prevent damage to equipment and avoid sudden motion in actuators—enhancing safety and extending system life.

Available in multiple sizes and configurations, the MS-DL valves are ideal for applications where controlled pressurization is critical. Their modular design allows seamless integration with other MS series components including filters, regulators, lubricators, and shut-off valves.

Key Features:

• Smooth, gradual pressure increase to protect equipment

• Manual or electric actuation options depending on series

• High flow rates and compact footprint

• Available in sizes: MS4, MS6, MS6N, MS4N, MS12

• NPT and metric thread options

• Compatible with modular MS Series air prep systems
