There are many ways to use screw drives in fittings and valve technology, for example in:

  • Electromechanical actuators
  • Control valves
  • Control valves
  • Stem gate valve
  • Rotary actuators
  • Linear drives
  • Stuffing box shut-off valves

The specialty of these applications is that the materials usually have to be resistant to chemicals and acids. In addition, the screw drives are often heavily loaded. In many cases, valve spindles are thicker than the drive thread in some places. Therefore, the production methods of thread whirling and thread cutting are ideal here. The spindles can then be hot-formed, manufactured “from solid” or assembled from two parts.
