KTM Model Gratite Seat Hi-Temp
KTM Gratiteseat ball valve operates across an impressive range of temperatures, boasts outstanding performance and a reliability, making it ideal for high pressure, anti-corrosion and other key process lines.
Features
1.Hard graphite with excellent self-lubrication and anti-corrosion properties is adopted to the seat and flexible graphite to the cushion seal
2.Hard graphite seats and the graphite packing ensure a wide operating temperature range from -29°C to 500°C
3.Gratite offers superior cost effectiveness in comparison to the metal seated valves
4.High resistance to thermal shock prevents the cracking caused by thermal shock seen in ceramics
5.With high conductivity, Gratite® has an anti‑static function
6.Blowout-proof stem (ASME Class 600 optional)
7.A two-piece body construction makes maintenance easier
8.The product features a fire safe design
9.Easy actuator mounting
10.It can be used for both flow directions (ASME Class 600, DN50 to DN100 is unidirectional flow).
11.Gratite boasts outstanding sealing characteristics
