Socket Weld Ball Valve

Socket Weld 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 performance parameters of floating ball valves?

·The main performance parameters of floating ball valves can be summarized as follows:

·1. Structural features

·Valve seat seal design: Provides effective sealing to ensure that the medium will not leak.

·Reliable inverted seal valve stem: Enhances the sealing performance of the valve, especially in high pressure or high temperature environments.

·Fireproof static electricity function: A conductive spring is set between the valve stem and the valve body and between the valve stem and the ball to prevent ignition of flammable media due to static electricity.

·Automatic pressure relief and locking device: Ensure that the valve can automatically relieve pressure under abnormal conditions and lock in a safe position.

·2. Material selection

·Ordinary carbon steel series (WCB&A105): Suitable for general working conditions.

·Stainless steel series (304,316): Stronger corrosion resistance, suitable for corrosive media such as chemicals and petroleum.

·Low temperature steel series (LCB, LCC): Suitable for low temperature environments.

·Sulfur-resistant series: Suitable for sulfur-containing media.

·3. Technical parameters

·Nominal diameter dn (mm): 50~300, to meet the needs of different pipeline sizes.

·Nominal pressure pn (mpa): 1.0, 1.6, 2.5, 4.0, 6.4, etc., select the appropriate pressure level according to the use scenario.

·Light, flexible and reliable operation: quick opening and closing (opening and closing time is only 0.05~0.2 seconds).

·4. Sealing performance

·Good sealing performance: soft alloy sealing ring is used, and the service life can reach more than 300,000 times.

·Wide range of application: can be used to cut off or connect a variety of media in the pipeline, such as water, steam, oil, etc.

·5. Other performance

·Strong explosion-proof performance: ensure that the valve will not break or leak under abnormal circumstances.

·Small flow resistance: Since the inner cavity of the valve body is straight-through, there is no dead zone and the medium can flow smoothly.

·The above parameters and characteristics are the main performance parameters of the floating ball valve. The specific parameters may vary depending on the model and manufacturer. In actual application, the appropriate floating ball valve should be selected according to the specific use scenario and needs.
