Product Description

The ball and seat of the metal-seated ball valve exclusively utilize a metal-to-metal sealing mode. To cater to diverse service conditions and user requirements, various advanced hardening technologies for the ball and seat are employed. These include 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 heat resistance of the sealing face material can reach between 540°C and 60°C, with a maximum 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 three surface treatment techniques: hard chrome plating, vacuum coating, and tungsten-titanium alloy and stellite alloy pile-up welding, to meet heat and wear resistance requirements. 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 prepressing seat, which ensures the absolute reliability of the seal and stability of operating torque. It guarantees absolute safety, sealing reliability, and operational flexibility and convenience in structural design.
