Festo Magnet Valve 558369 Corr. Lely 9.1138.0908.0

Festo Magnet Valve for Lely A3 / A4

The Festo Magnet Valve is a high-speed pneumatic solenoid valve used within the control manifold of the Lely Astronaut milking robot. This valve is a critical component for managing air distribution to the robot's arm cylinders and gripper mechanisms, ensuring precise and reliable movement during the 24/7 milking cycle.

Product Identification

Key Features

• Industrial Precision: Manufactured by Festo to meet the high-repetition demands of robotic automation.
• Rapid Switching: Optimized for low latency, allowing the robot arm to respond instantly to the Teat Detection System (TDS).
• High Durability: Features a robust housing resistant to the moisture and cleaning chemicals found in the milking stall.
• Low Power Consumption: Designed to operate efficiently within the 24V DC control architecture of the Lely system.

Technical Insight

The Festo 558369 is typically part of a valve terminal assembly. If you are experiencing "Arm Timeout" or "Cylinder Move Errors," it is important to check:

1. The Solenoid Coil: Often identified by the 558351 number, ensure it is receiving the correct voltage signal.
2. Exhaust Ports: Check for clogs in the silencers that may be causing back-pressure and slowing down the valve's response.
3. Internal Seals: If you hear a constant "hissing" or air leak from the manifold, the internal spool seals of this magnet valve may be worn.
