The Festo MS6-DL-1/2 is a soft-start valve designed to pressurise pneumatic systems during startup safely. It allows air pressure to build gradually before switching to full flow, helping prevent sudden movement, pressure shocks, or damage to connected equipment. This makes it worthwhile in compressed air systems where controlled startup is critical. It combines a pilot-operated spring return mechanism, ensuring predictable behaviour when air supply is applied or removed.
When the system starts, the valve slowly increases the downstream pressure. Once the preset pressure level is reached, the valve opens fully and allows normal airflow. If supply pressure drops or is shut off, the spring return brings the valve back to its safe position. This helps reduce wear on cylinders, valves, and actuators while improving overall system safety.
The valve supports high airflow, making it suitable for systems with demanding air consumption.
