Metal Seat Ball Valve
Metal seated valve ball and seat is the critical parts of metal seated ball valves. It is designed for extreme high pressure, temperature and abrasive conditions, such as cutting off or connecting solid granules, melted slurry, coal power, scalding cinder, steam water or other liquid etc. Therefore it has the feature of anti-static construction, extra tough coating, full bore and reduced bore, fire safe feature complying API607, and reliable sealing performance.
Metal Seat and Ball are made from base metals coated usually with hard chrome, tungsten carbide, stellite and Ni60. We have both thermal spray coating and cold spray coating available such as Laser Cladding, HVOF (High Velocity Oxy Flame) Coating, Oxy-acetylene flame spray, and plasma Spray process.
The complete range of forged valves is designed in two or three bolted pieces with a solid double trunnion configuration and two independent seats for an easy bidirectional sealing,to ensure the great Testing level of tightness and reliability under high pressure and temperature conditions in all critical isolation services.
