Heavy-Duty, Enclosed Gear Assemblies
TRUMBULL MITER GEARS are designed to fulfill the following primary functions:
- To be used as an add-on component to Trumbull Floorstands or Pedestals
- To be mounted directly to valves where a 90 degree change in the input shaft direction is required
- For use as a stand-alone component in a valve operating assembly with rotating elements, such as extension stems, where the installed conditions require one or more 90 degree changes of direction
Housings are cast 316 stainless steel or ductile iron 65-45-12 with a Tnemec N140-1211 two-part epoxy, NSF-61 certified exterior coating. The gears are case hardened steel; the gear shafts and fasteners are 316 stainless steel.
Trumbull Miter Gear Assemblies are provided standard with a recessed grease fitting for easy maintenance and Buna-N O-ring seals on each end adapter.
