2 Piece Floating Ball Valve

2 piece floating ball valves are manufactured in accordance with API 6D. The valve is configured in a forged bolted two-piece split-body design with a small diameter, suitable for medium/low pressure working conditions. Characterized by simple design, the valve seats are directly inserted into the body.
The upstream flow pressure pushes the free-floating ball against the downstream seat-the resulting compression provides a perfect leak-free sealing solution.
The stem is connected at the top of the ball and allowing the valve to open and close with a quarter-turn movement.
Material selection is fully customizable to meet the customer's project specifications and several unique features are available offering an enhanced technical solution suitable for aggressive offshore environment and corrosive and abrasive fluids.

What are the main materials of floating ball valves?

The main materials of floating ball valves can be divided according to different parts of the valve body and different usage requirements. The following is a detailed summary of the main materials of floating ball valves:

Valve body:

The valve body is the main part of the floating ball valve, and its material directly affects the overall performance and durability of the valve. Common valve body materials include cast iron, carbon steel, stainless steel, etc. Common materials for stainless steel series are 304 and 316, which have excellent corrosion resistance and mechanical properties and are suitable for special media and corrosive environments. Carbon steel series such as WCB and A105 are suitable for general industrial use.

Ball:

The ball is a key component of the floating ball valve, which is used to control the flow of the medium. The material of the ball also affects the performance and sealing effect of the valve. Common ball materials include stainless steel, copper and aluminum. Stainless steel balls have excellent corrosion resistance and mechanical properties and are suitable for a variety of media. The copper ball has a smooth surface and good corrosion resistance, but the price is relatively high.

Seal ring:

The seal ring is another key component of the floating ball valve, which is used to ensure the sealing of the valve in the closed state. The materials of the sealing ring are usually polytetrafluoroethylene (PTFE), rubber, etc. These materials have good sealing performance and wear resistance, and can maintain a stable sealing effect under different media and pressures.

Other parts:

In addition to the above main components, the floating ball valve also includes parts such as valve stem and valve core. The materials of these parts are usually selected according to the specific needs and working environment of the valve. For example, the materials of the valve stem and valve core can be stainless steel, copper, etc. to ensure that they have good mechanical properties and corrosion resistance.

In summary, the main materials of the floating ball valve include metal materials such as stainless steel, carbon steel, cast iron, copper, aluminum, and non-metallic materials such as polytetrafluoroethylene and rubber. The choice of these materials depends on the specific application scenarios, working environment and media requirements of the valve. By selecting the right materials, it can be ensured that the floating ball valve has excellent performance, reliability and durability.
