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.
  • Use of Polymide (Nylon) tubing that is rated to less than 120oC,  so in the event of fire, air line can soften and release any air in the systems and close the poppet.
