Fire Rated 2-way Ball Valves
SP 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.

- Valve shall be a three-piece “swing-out” body design.
- Valves meet ASME B16.34.
- Stem assembly accommodates IMI PBM Direct Mount Actuation for accurate alignment and increased cycling life.
- Full port design.
- Valves are rated to full vacuum.
- Optional Fusible Link – A Spring Return Handle unit can be equipped with optional fusible links and/or electro thermal links specified to a customer’s required melt temperature, which closes the valve during fire conditions.
