Key Features

• Premium Stainless Steel Material

Manufactured from high-grade stainless steel including CF8, CF8M, CF3M, 304, 316, and custom grades. Excellent resistance to water, steam, oil, chemicals, and marine environments.

What’s the best material for a valve disc?

Stainless steel is the most common valve disc material because of its anti-corrosive, anti-heat and anti-contamination properties. The Baoding Guokun stainless steel casting valve disc is made as investment casting process, or lost wax techniques that results in a significantly improved surface finish & casting tolerance and valve disc quality than other sand cast stainless steel valve disc and bronze valve disc.

• Precision Casting & Machining

Produced via investment casting or lost‑wax casting for tight dimensional accuracy. CNC machined sealing surfaces guarantee perfect flatness, smooth finish, and zero leakage.
