Metal Seat Ball Valve

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.

Over the years, we have developed a unique ball lapping technology for the coated ball and seat. Through simultaneous same and different direction of rotation, the ball and the seat result in perfect roundness and fitness, achieving “Zero Leakage”
