4. Application Scenarios
- Low - platform Design: The low - platform structure simplifies the overall height of the valve, making it suitable for installation spaces with height restrictions. It is easy to match with pipelines and other equipment, and the compact design helps save installation space.
- Integral Casting: The valve body adopts integral casting technology, which has high structural strength and good pressure - bearing capacity. It can effectively resist the impact of medium pressure and reduce the risk of valve body damage and leakage.
- Sealing Structure: Equipped with precision - machined ball and valve seat, combined with reliable sealing materials (such as PTFE), it can achieve excellent sealing performance, effectively preventing medium leakage and ensuring the normal operation of the pipeline system.
- Manual Operation: With a manual handle operation, the operation is simple and direct. By rotating the handle 90 degrees, the on - off control of the medium can be quickly realized, and the operation torque is small, which is convenient for on - site personnel to operate.
- Flow Control: The ball valve structure enables efficient flow control. It can realize full - bore flow conduction, with small flow resistance, and can also perform certain flow regulation functions (within a certain range) to meet the different needs of pipeline systems.

- General Industrial Pipelines: Widely used in general industrial fluid transportation pipelines, such as water supply and drainage, chemical liquid transfer, and general medium pipeline systems in factories. It can meet the basic medium on - off and simple flow control needs.
- Light Industry and Civil Engineering: In light industry production lines (such as food, beverage, and pharmaceutical industries) and civil building pipeline systems (such as heating, water supply pipelines), it is used to control the flow of media, with the advantages of simple operation and reliable sealing.
- Low - Pressure Pipeline Systems: Suitable for low - to - medium pressure pipeline systems, can play a good role in medium control in pipelines with pressure levels such as PN16 and PN25, ensuring the normal operation of the pipeline system.
- Design Standards: Complies with relevant national and industry standards for flanged ball valves, such as GB/T 12237 (Chinese standard) and API 608 (international general standard for partial reference), ensuring that the product design meets basic safety and quality requirements.
- Quality Management: Manufacturers generally have ISO 9001 quality management system certification, which ensures that the production process from raw material procurement, processing and manufacturing to product inspection is strictly controlled, and the product quality is guaranteed.
- Testing and Inspection: Undergoes strict factory tests, including pressure test (shell test and seat test), leakage test, etc. These tests ensure that the valve can operate reliably under rated working conditions and meet the requirements of pipeline system use.
- Material Certifications: For stainless steel valve bodies, relevant material certification documents can usually be provided to prove that the material meets the corresponding quality and performance standards (such as 304 stainless steel compliance with GB/T 20878 standards).
