Fire Rated Tank Bottom Valve
Industrial Tank Bottom Series 6, 1/2” – 3”
IMI PBM’s Fire-Rated valves can accommodate flammable media in industrial process environments. These API-607 qualified valves feature a backup metal seat against which the ball seals if the normal polytetrafluoroethylene seats melt under fire conditions. This metal seal allows only limited leakage under fire conditions.
- Fire Rated, tested to API-607.
- FT Series Fire Rated Tank Bottom valves have o-rings.
- Valves shall be a three-piece “swing-out” body design.
- Valves meet ASME B16.34 in appropriate materials and ends.
- Pad radius facilitates efficient drainage and reduces the pocket area above the ball.
- Upstream and downstream bubble-tight sealing capability allows valve body cleaning, purging, and draining.
- Stem assembly accommodates IMI PBM Direct Mount Actuation for accurate alignment and increased cycling life.
- Available in Angle Stem versions for applications where automation may interfere with tank head or jacket.
- Valves are rated for full vacuum.
- Standard bottom-entry stem provides protection from inadvertent stem removal. Engagement between the slot and ball is specially designed for high torque applications.
