The metal seated ball valve features a metal-to-metal sealing mode between the ball and seat. Depending on the service conditions and user requirements, various advanced hardening technologies for the ball and seat are available, such as HVOF coating, nickel-base alloy spray welding, high nickel alloy spray welding, nickel-base alloy tungsten carbide alloy spray welding, and cobalt-base hard alloy spray welding. Typically, the sealing face material can withstand temperatures ranging from 540°C to 60°C, with a maximum heat resistance of up to 980°C. This material also exhibits excellent wear and impact resistance. The seat is made of stainless steel with stellite alloy pile-up welding, while the ball is constructed from stainless steel and undergoes three surface treatment techniques: hard chrome plating, vacuum coating, and tungsten-titanium alloy and stellite alloy pile-up welding. These treatments ensure the ball meets the necessary heat and wear resistance requirements. Our ball manufacturing process is innovative, achieving high-precision and ultra-mirror surface processing of the ball. Another notable feature of the metal seated ball valve is the spring preloaded seat, which guarantees absolute sealing reliability and stable operating torque. This design ensures absolute safety, reliable sealing, and convenient operation.
