This O-type floating valve ball serves as the core opening and closing component of floating ball valves. It adopts a standard circular through-hole structure and achieves medium on-off control through 90-degree rotation around the stem axis. The component generates low flow resistance during operation due to its straight-through flow passage design, and supports fast switching actions within seconds. It is specifically designed for use in ANSI-standard floating ball valves, and matches corresponding valve body cavity and seat dimensions per ANSI B16.34 dimensional requirements. The spherical surface is processed via precision grinding and polishing to achieve specified surface roughness, which forms a sealing pair with matched valve seat materials. As a replaceable spare part for ball valves, it can replace worn or damaged valve balls in existing pipeline systems to restore the sealing and flow control performance of the valve. The product is produced with dimensional tolerances controlled per corresponding industrial standards, ensuring interchangeability with valve bodies of the same specification from compliant manufacturers.
This valve ball is available in multiple stainless steel grades to adapt to different medium properties and working conditions. Common material options include CF8 (equivalent to SUS304), CF8M (equivalent to SUS316), as well as low-carbon variants such as CF3 and CF3M. Each material grade complies with corresponding ASTM A351 or JIS material standards, and its chemical composition can be verified via positive material identification (PMI) testing. The product follows ANSI standard dimensional specifications for floating ball valves, covering common nominal sizes from DN15 to DN100. Custom dimensions, special material grades and surface treatment options are available for special operating requirements such as strong corrosion or high abrasion conditions. All production processes follow ISO 9001 quality management system requirements, with traceable production batches and material heat numbers for each unit.

First, urban water supply and drainage and municipal pipe networks. This valve ball is suitable for water supply, sewage treatment and municipal pipeline systems. When matched with corresponding seat materials, it achieves stable on-off control of water flow under conventional pressure and water quality conditions.
Second, petroleum and natural gas transmission systems. The component is applied in oil and gas pipelines, storage facilities and refining equipment. It works with fire-safe and low-emission valve seat designs to cut off flammable and explosive media, and adapts to medium-high pressure working conditions in the oil and gas industry.
Third, HVAC and thermal circulation systems. It is used in heating, central air conditioning and thermal pipeline networks. The straight-through structure supports rapid on-off control and maintains stable structural performance in hot water and steam medium conditions.
Fourth, general industrial fluid pipelines. It is widely used in conventional gas and liquid pipelines in chemical, power and light industrial production systems. As a core on-off component, it supports on-site maintenance and replacement to meet continuous production operation requirements.
This valve ball is compatible with water, oil, gas, steam and weakly corrosive fluids. The actual compatibility depends on the selected material grade and matching seat material. It is suitable for clean and conventional medium working conditions when used with standard PTFE or RPTFE seats. For strongly corrosive media, special material grades can be selected accordingly.
The O-type floating ball is mainly used for fast on-off control and forms a full seal when closed. The V-type ball is designed for flow regulation and has a shearing effect on media. O-type balls are selected for conventional shut-off applications, while V-type balls are used for flow proportional control scenarios.
Stainless steel O-type valve balls can adapt to certain high temperature and high pressure conditions. The specific applicable temperature and pressure limits depend on the material grade of the ball, the seat material and the valve body pressure rating. For working conditions beyond conventional ranges, customized material and heat treatment schemes can be provided.
The actual service life of a valve ball varies with medium properties, working pressure, switching frequency, installation accuracy and daily maintenance. Under normal working conditions and regular maintenance, the component can maintain stable performance for a long period. Abrasive media and frequent switching operations will reduce the service life.
