Lely MQC-C2 Media Separated Valve

Media Separated Valve 1/8" for Lely Astronaut

The Media Separated Valve (1/8") is a specialized solenoid valve used in Lely Astronaut robotic milking systems and calf feeders. Unlike standard valves, a "media-separated" design uses a diaphragm to isolate the internal mechanical parts (plunger, spring) from the fluid or gas being controlled. This is essential for handling sensitive or aggressive media like chemicals, milk, or water without the risk of corrosion or cross-contamination.

Product Specifications

System Compatibility

This valve is utilized across several Lely platforms where high hygiene or chemical resistance is required:

• Lely Astronaut A2, A3, A4, A5: Often used in the water manifold, teat spray systems, or chemical dosing lines.
• Lely Calm Calf Feeders: Used for controlling the flow of milk or water to the drinking station.
• Lely Discovery / Collector: Can be found in the water spray or cleaning modules.

Key Benefits of Media Separation

• Corrosion Protection: Aggressive cleaning agents or hard water never touch the valve's electromagnetic drive, significantly extending its lifespan.
• Hygiene & Purity: By eliminating "dead spaces" where milk or bacteria could accumulate, this valve ensures a higher level of sanitation.
• Reduced Blocking: Since the actuator is outside the fluid path, the valve is less likely to fail due to small particles or mineral buildup in the water supply.
• Reliability: Designed for the high-frequency switching required in robotic 24/7 operations.

Maintenance Insight

When replacing this valve, ensure the O-rings and electrical connector are seated correctly to maintain the IP-rating of the assembly. If you notice a decrease in spray pressure or a "leaking" teat sprayer when the robot is idle, the internal diaphragm of this valve may be worn and require replacement.
