The Flow-Tek Series 19 is a versatile Segmented Ball Valve designed for throttling or on-off applications in various industries including pulp & paper, chemical, power, oil & gas, and mining. 

The valve features a characterized ball segment for high rangeability with splined stem connection for precise control, maintenance friendly segment-stem assembly, low friction shaft and thrust bearings for longer life, integral actuator mounting pads, and interchangeable seats. 

Valve Body

  • One piece body design which offers greater rigidity against fluctuating pipe loads
  • Eliminates the leak path associated with two piece body designs
  • Available in Flangeless and Flanged ends

Ball Segment

  • Carefully designed with characterized V-port to offer rangeability in excess of 300:1, ideal for throttling applications in high consistency pulp services or slurry applications
  • Perfectly ground spherical surface with rounded edges ensure lower operating torques for metal seated valves
  • Hard coated spherical surface prevents galling
  • The segment is carefully designed for optimum flow
  • The seat is supported during higher openings to prevent rocking motion and possible failure of the valve


Ball – Stem Connection Seat

  • Close-fit splined connection between stem and the segment offers extra strength with no lost motion or dead band
  • Perfectly oriented, specially designed shaft pin facilitates self-alignment of the ball segment while simplifying the assembly and disassembly during routine maintenance



  • Available with a metal seat and soft seat
  • Directs the flow away from the sealing area
  • Pressure energized seat design offers excellent sealing even at very low differential pressures
  • Self-aligning seat is independent of external pipe loads and offers excellent sealing even in adverse conditions
  • Standard metal seat has hard-faced seat surface with Stellite overlay on 316 Stainless Steel base material
  • Standard soft seat design uses Tek-Fil® to maintain exceptional chemical and heat resistance
  • Flow-Tek's Tek-Fil® provides higher compressive strength, lower co-efficient of friction, superior abrasion and wear resistance, lower permeability, lower porosity, and reduced cold flow



  • Stem and end post bearings are low friction and maintenance free
  • Made of wear resistant PTFE compound supported by metal fabric or thick walled metal depending on the pressure drop
  • Additional thrust bearing on stem collar for high pressure applications eliminates unbalanced axial load for consistent high performance and precision control
Class 150/300/600
