N-Line Axial Flow Control Valve
Stem Drive Mechanism


The unique application of a Trunnion into
the drive prevents the radial movement of
the cage sleeve and subsequent motion
loss.  The drive accurately converts rotary
stem motion to a reliable linear motion in
the trim.  (Patents applied for and pending.)

 

For applications that involve surface build-up of solids or coatings, we offer our self cleaning drive shaft and Trunnion configurations.  This open track allows the drive and Trunnion blocks to scrape the track clean of any deposits from the flow media.  (Patents applied for and pending.)
