Stem Nut Machining

Stem nuts are the most common reason for failures in motor operated valves. These nuts may seem insignificant, but as the drive element between the valve and the actuator, they are responsible for opening and closing valves. Stem nuts are the most common reason for failures in motor operated valves. Action Automation can thread for any size actuator in our machine shop and offer quick turnaround times at a fraction of the cost from OEM’s. We maintain inventory for all Limitorque actuator models.

Our stem nut machining services include:

  • Threads for single, double and triple lead threads
  • 29-degree standard acme threads
  • Stub acme threads
  • Metric threads
  • Internal threads for stems that have rolled threads
  • Modified stub acme threads
  • Bore and key steel stem nuts
  • New yoke nuts for manually operated valves
  • Wire EDM splines in nuts on the OD and ID for any configuration
