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.
- 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.
