TVI Valves
  • UNP has a unique design plug valves specifically to provide very low torque against PFA lined plugs available as standard worldwide.
  • UNP offers lining options instead of standard PFA or FEP Lined Plugs to achieve very low torques.
  • UNP has GTEFCOR and CERCOR Plug Options for abrasive applications and these options will help against conventional plug lining options of PFA or FEP which may wear out in abrasive applications.
