The ball and seat of the metal-seated ball valve utilize a metal-to-metal sealing mode. Depending on the service conditions and user requirements, various advanced hardening technologies can be applied to the ball and seat, including:

» High-Velocity Oxygen Fuel (HVOF) coating
» Nickel-based alloy spray welding
» High nickel alloy spray welding
» Nickel-based alloy tungsten carbide alloy spray welding
» Cobalt-based hard alloy spray welding

Generally, the heat resistance of the sealing face material can reach 540°C to 600°C, with a maximum value of 980°C. The sealing face material also exhibits excellent wear resistance and impact resistance.
The seat is made of stainless steel with Stellite alloy pile-up welding. The ball is made of stainless steel and undergoes one of three surface treatment techniques to meet heat and wear resistance requirements:

» Hard chrome plating
» Vacuum coating
» Tungsten-titanium alloy and Stellite alloy pile-up welding

Our ball manufacturing process is innovative, achieving high-accuracy and super mirror surface processing of the ball. Another feature of the metal-seated ball valve is the spring preloading seat, which ensures the absolute reliability of the seal and stability of the operating torque. This design ensures absolute safety, sealing reliability, and operational flexibility and convenience.
