Marine API Floating Ball Valve

About product

The marine API floating ball valve is a versatile valve design where the ball inside the valve is allowed to float. This unique feature enables the ball to move and adjust its position under the influence of the medium’s pressure. When the pressure increases, the floating ball is pushed against the outlet section, creating a secure and tight seal to prevent any leakage.

The API floating ball valve is designed and manufactured in accordance with industry standards such as API 6D and API 608. These standards ensure that the valve meets strict criteria for quality, performance, and safety. By adhering to these standards, the valve is constructed using suitable materials, undergoes rigorous testing, and is built to withstand demanding operating conditions.

Product Detail

Marine American Standard Floating Ball Valve for Sale

The API floating ball valve is equipped with a ball as its closing element. This ball rotates around the center line of the valve body to control the flow by either opening or closing the valve. It is important to note that ball valves are not suitable for throttling applications and are primarily used for cutting off, distributing, and changing the flow of pipeline intermediates.

When installing a ball valve, it is generally recommended to position it horizontally within the pipeline. This orientation ensures optimal performance and efficient operation.

Furthermore, the selection of materials for the ball valve is crucial to ensure compatibility with specific media. Different materials can be chosen based on the nature of the fluid being handled. For example, suitable materials may include those appropriate for water, steam, oil, nitric acid, acetic acid, oxidation mediums, urea, and various other media.

Marine API Floating Ball Valve Features

  • 2 Pieces/3 Pieces Body: The ship valve body is constructed in either a 2-piece or 3-piece configuration. The 2-piece body consists of two main pieces that are bolted together, while the 3-piece body consists of three main pieces. These designs offer advantages in terms of assembly, maintenance, and accessibility.
  • Full & Reduced Bore: The API ball valve is available in both full and reduced bore options. Full bore valves have a larger internal diameter, allowing for maximum flow capacity. Reduced bore valves have a smaller internal diameter, which can be suitable for applications where flow capacity is not a primary concern.
  • Full & Reduced Bore: API floating ball valve is available in both full and reduced bore options. Full bore valves have a larger internal diameter, allowing for maximum flow capacity. Reduced bore valves have a smaller internal diameter, which can be suitable for applications where flow capacity is not a primary concern.
  • Anti-Static Device: To prevent the build-up of static electricity, the valve is equipped with an anti-static device. This feature allows for safe operation in potentially hazardous environments and helps to prevent static discharge.
  • Blow-Out Proof Stem: The stem of the ball valve is designed as a blow-out proof stem. This means that even under high-pressure conditions, the stem is securely retained within the valve body, minimizing the risk of stem failure or ejection.
  • Low Fluid Resistance: The valve has minimal fluid resistance, with a resistance coefficient equivalent to a pipe segment of the same length. This characteristic ensures efficient flow and minimizes energy loss.
