ASTM B148 Nickel aluminum bronze and ASTM B62 C83600 tin bronze are available.
The flange face can be raised face and flat face. FF are more commonly adopted.
Structure: Bolted bonnet-bolted gland-outside screw stem, yoke, union bonnet-screw gland-inside screw rising stem.
Full bore and reduced bore are both available; reduced bore is generally used for size below 2 inches, fugitive emission gate valve.
Suitable for sea water, corrosion resistance for long life service.
A manual bronze shut-off gate valve is typically made through the following process:
1. Material selection: High-quality bronze alloy is chosen for its corrosion resistance and durability. high temperature gate valves
2. Casting: The selected bronze alloy is melted and poured into a mold to create the valve body, bonnet, and gate. The mold is designed to have the desired shape and dimensions of the valve. api 6d ball valve
3. Machining: After the casting process, the valve components are machined to achieve precise dimensions and smooth surfaces. This involves cutting, drilling, and shaping the bronze parts using specialized tools and machinery, duplex stainless steel ball valve.
4. Assembly: The machined components, including the valve body, bonnet, gate, stem, and packing gland, are assembled together. The gate is attached to the stem, which is connected to the valve handle or handwheel.
5. Testing: The assembled valve undergoes rigorous testing to ensure its functionality and reliability. This includes pressure testing to check for leaks and proper sealing when the valve is closed. forged ball valve
6. Finishing: The valve is cleaned, polished, and coated with protective finishes to enhance its appearance and resistance to corrosion.
Overall, the manufacturing process of a manual bronze shut-off gate valve involves casting, machining, assembly, testing, and finishing to create a reliable and durable valve for controlling the flow of fluids. carbon steel gate valves
