Internal Drain Valve


The ITV1-AO 25mm internal valve with integral elbow, has been designed for use on aircraft refueller tankers which have small sample or drain lines.

Features & Benefits
  • Normal fitting in the sump is a 25mm BSP socket.
  • Flow is outwards only.
  • The elbow incorporates a shear groove above the pipe attachment aperture to ensure a breakaway (in the event of damage) at that point.
  • Valve poppet, spring and shaft are all attached above the shear point to ensure the continued containment of product in the tank.
  • In the event of fire the air line will soften at 80oC and release any air in the systems and close the poppet.
