    • Magnet Valve Spray 1/4" (24V DC)

    This Magnet Valve Spray is a heavy-duty, chemical-resistant solenoid valve specifically designed for the teat spraying systems of Lely Astronaut A2, A3, and A4 robots. Given the harsh nature of teat disinfectants (iodine, chlorhexidine, or lactic acid), this valve is constructed with premium materials to prevent corrosion and ensure a long operational life.

    Key Features

    • Premium Chemical Resistance: The combination of a Stainless Steel housing and FKM (Viton) seals makes this valve impervious to the aggressive chemicals found in post-milking teat dips.
    • Normally Closed Operation: The valve remains securely closed until it receives a 24V electrical signal, preventing accidental leakage or waste of expensive teat spray.
    • Integrated Package: Comes complete with the 24V DC spool (coil) and the electrical connector, making it a "plug-and-play" replacement for the original Lely component.
    • Optimized Flow: The 3mm orifice and 0.2 Kv value provide the precise pressure and volume needed to achieve a consistent spray pattern for effective teat coverage.

    System Compatibility

    While specifically listed as the corresponding part for the Lely A2 (9.1138.0407.3), this 1/4" valve is widely used as a robust upgrade or replacement for teat spray manifolds in:

    • Lely A2
    • Lely A3 / A3 Next
    • Lely A4

    Maintenance Insight

    If your teat spray pattern becomes weak or if the sprayer continues to "drip" after the cycle is finished, the internal FKM seal may be obstructed by debris or mineral buildup.

    • Pro Tip: When installing the 1/4" connections, ensure you use a thread sealant compatible with your teat dip chemicals to prevent leaks at the housing.
