A sealant applying machine for applying sealant to can lid members comprising a plurality of circumferential spaced sealant applying stations whereat sealant material is applied to a lid member and a rotatable carriage means for supporting and carrying the stations around the machine. Each station comprises a lid holding means for holding and rotating a lid member during application of sealant material to the lid member, a sealant dispensing means mounted adjacent the lid holding means for applying sealant material to the lid member, and mounting means for holding the sealant dispensing means in fixed, non-movable relationship to the lid holding means during application of sealant material to the lid member. A nozzle means has a sealant dispensing opening, a needle valve seat surface and spring biased needle and a sealant flow passage for enabling flow of sealant material onto the lid member. A needle valve acuator solenoid means is mounted in the intermediate housing portion and is operatively connected to the needle valve.
