KTM Ball Valves
Gratite ® Seat, Hi-Temp Ball Valves
KTM’s Hi-Temp ball valves are designed
to operate within a temperature range
from -50ºF to 932ºF. 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
• 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.
