Angle stem tank bottom valves


  • Unique low torque Flexi-seat design maintains tight shut-off through pressure and temperature
    cycles is standard for valves without cavity fill
  • ISO 5211 mounting pad for direct mounting of handle, gear operator, manual override, or actuator
  • An extremely tight fit drive between the stem and ball provides accurate and repeatable shut-off and control
  • Cavity fill option includes solid seats without grooves to prevent media being trapped in the cavity between the seats when the valve is open
  • Optional T-port ball provides draining of the cavity between the seats when the valve is closed
  • When combined, cavity fill and T-port ball option provides the best solution to avoid media inside
    the valve
  • Every valve is 100% factory tested before it is packed and shipped


  • Complete package reliability and single source responsibility with Metso’s full range of actuators, switches, and intelligent valve controllers.
  • Cavity fill and T-port options for the JT series ensure lowest possible dead volume and full draining of media from the valve
