Introduction
Metal Seated Trunnion Ball Valve
Designed to provide peak performance in elevated temperature applications, the Metal Seated Trunnion Ball Valve features hard faced a ball and seat to minimize wear and extend valve life. The hard face coating is applied using a High Velocity Oxygen Fuel (HVOF) process and can be either tungsten carbide or chrome carbide. Its adjustable gland packing box with multiple stem sealing helps our customers meet the stringent ISO 15848 fugitive emissions test requirements.
