KTM’s Hi-Temp ball valves are designed to operate within a temperature range from -50°F to 932°F. They incorporate valve seats of Gratite® material (a bonded composite of graphite) formed with flexible graphite which is used to cushion seal. The result is a seat with physical properties that are far superior to conventional ball valve seats of carbon graphite construction.
Features & Benefits:
More economical than metal seat.
High resistance to thermal shock.
High electro conductivity helps eliminate need for grounding device.
Seats and seals are virtually chemically inert.
Blow-out proof stem.
Two-piece body construction.
Fire-safe.
Easy actuator mounting.
Bi-directional flow.
