DRAWINGS & DOCUMENTS
- Hard graphite with excellent self-lubrication and anti-corrosion properties is adopted to the seat and flexible graphite to the cushion seal
- Hard graphite seats and the graphite packing ensure a wide operating temperature range from -29°C to 500°C
- Gratite offers superior cost effectiveness in comparison to the metal seated valves
- High resistance to thermal shock prevents the cracking caused by thermal shock seen in ceramics
- With high conductivity, Gratite® has an anti‑static function
- Blowout-proof stem (ASME Class 600 optional)
- A two-piece body construction makes maintenance easier
- The product features a fire safe design
- Easy actuator mounting
- It can be used for both flow directions (ASME Class 600, DN50 to DN100 is unidirectional flow).
- Gratite boasts outstanding sealing characteristics
