Are you talking about the valve buttons or finger buttons (the things on top of the valve stems that you place your fingers on to push down)?
I ordered new ones just like that for my Getzen from Mouthpiece Express (<url>https://mouthpieceexpress.com/catalog/advanced_search_result.php?search_in_description=1&keywords=finger+buttons</url>), but you can find them almost anyplace (Edwards, Allied Supply, Amazon, Ebay, etc.). |
The caps on the top of the actual valve block. |

I guess another question would be - when did they stop making them this way. Check old Conn, Holton, and King catalogs - they were all set up this way placing the felt or cork under the finger button. |

Be careful about the precise dimensions, because the amount of down-stroke valve travel is dependent on the height of the top of the cap - and the felts / spacers placed on the underside of the valve button. _________________ Most Important Note ? - the next one !
KNOW (see) what the next note is BEFORE you have to play it.
PLAY the next note 'on time' and 'in rhythm'.
Oh ya, watch the conductor - they set what is 'on time'. |

It's an old-fashioned top-knot style cap. Nothing mysterious, it's out of fashion. It may come back. _________________ "Strive for tone." -John Coppola

I imagine a shop with a quality lathe can cut down the outer part of a standard valve cap to make them. |

My Schagerl rotary, new a couple of years ago, has exactly that. I have no idea if it's required/functional or what, but at least it's modern. _________________ Matt Finley https://mattfinley.bandcamp.com/releases

With rotary valves there are 2 true bearings that position and align the rotor body. The rotor has an arbor / axle at the top and bottom, and the caps have a pivot hole to accept the arbor - the actual lubrication for the movement of the rotor is at the arbor / pivot location. Air sealing around the outer section of the rotor and casing can be obtained with water / condensation. Rotary valves can become sluggish if oil or grease migrates onto the outer section of the rotor.
Oiling of the pivots is done by a removable cap, and by carefully dripping a little oil into the seam at the non-removable cap and the 'swing arm'. _________________ Most Important Note ? - the next one !

Bearing oil should be applied to the spindle bearings and rotor oil should be applied to the core of the rotor. _________________ www.divitt-trumpets.com
