Stainless steel ball valves are fast, practical, and durable quick-acting valves made of corrosion-resistant stainless steel such as 304 or 316. Easy to maintain and repair.Stainless Steel Flanged Ball Valve are among the most common types. You are welcome to request our samples, and we accept a minimum order quantity of 1 piece.
Carbon steel ball valves are used for media such as water, oil, and steam under general working conditions. They are suitable for non-corrosive environments with normal temperature and pressure. Their advantages are low cost and high strength.
Stainless steel ball valves are ideal for applications requiring corrosion resistance and high hygiene standards.Suitable media include water, food and beverages, natural gas, weak acids and alkalis.They perform well in humid,coastal,chemical,food and pharmaceutical environments.Advantages: rustproof and highly corrosion-resistant.
304: Contains chromium and nickel, providing sufficient rust resistance.
316: Includes molybdenum in addition to the composition of 304, offering significantly higher corrosion resistance.
304: Suitable for general water, air, and weak acids and alkalis.
316: Suitable for highly corrosive media such as seawater and salt spray, and resistant to rust.
304: water , HVAC, general chemical processing, food equipment.
316:coastal projects, medical equipment, highly corrosive chemical environments,pharmaceuticals.

316 is more expensive than 304, but offers better quality and greater durability.
It is most important for buyers to select the appropriate material based on different working conditions.
Use 304 in normal environments for high cost performance.
Use 316 for seawater, salt spray and highly corrosive media for enhanced durability.
Long periods of inactivity causing the ball and seat to seize up
Extremely high or low temperatures deforming the seals
Excessive force during installation leading to valve body deformation
Use of an unsuitable material for corrosive media (e.g., carbon steel or regular stainless steel instead of 316)Huadu Valve can provide solutions to all these issues.
We adopt scientific design, advanced production technology, high-quality materials, and comprehensive safety protection.
Our production process is as follows:CAD Drawing → Mould Making → Casting → Semi-finished Casting → Semi-finished Machining → Polishing → CNC Precision Machining → Drilling → Assembly → Pressure Testing → Painting → Packaging → Shipment→Engineering Unit
