API 6D Cast Steel Flanged Trunnion Mounted Ball Valve
Design Features
Trunnion-mounted structure: The ball is fixed by two trunnion bearings, effectively reducing the operating torque and ensuring stability under high pressure conditions.
Sealing system: It adopts a two-way or one-way sealing mechanism. The sealing materials include PTFE, reinforced polymers or metal-to-metal designs, allowing for the selection of appropriate sealing materials according to the working conditions.
Fireproof design: It complies with the API 607/6FA fireproof testing standards and is suitable for flammable environments.
Anti-static design: It provides safety guarantees in working conditions where static electricity is easily generated.
Multiple operation modes: It offers various options such as manual operation, gear operation, electric operation, pneumatic operation or hydraulic operation to meet the needs of different application scenarios.
Technical Specifications
Size range: 1/2" ~ 56" (DN15 ~ DN1400)
Pressure rating: 150LB ~ 2500LB (PN20 ~ PN420)
Temperature range: -196°C ~ 650°C
Materials: A216 WCB, A352 LCC, A351 CF8M, etc. The sealing materials include PTFE, RPTFE, PEEK, etc.
Connection method: Flanged connection, conforming to the ASME B16.5 and ASME B16.47 standards.
Application Fields
This valve is widely used in the following fields:
Petroleum and natural gas pipelines: It is suitable for long-distance pipelines, oil and gas field exploitation and transportation systems.
Chemical industry: It is used for handling corrosive liquids and high-temperature and high-pressure media.
Oil refineries: It controls fluid flow during the refining process.
Extreme temperature environments: Such as low-temperature liquefied natural gas (LNG) and high-temperature steam systems.
Manufacturing and Testing
Manufacturing process: It adopts processes such as casting, forging, welding and heat treatment, strictly complying with the API 6D and ASME standards.
Non-destructive testing: It includes ultrasonic testing (UT), radiographic testing (RT), magnetic particle testing (MT) and liquid penetrant testing (PT).
Pressure testing: The shell test pressure is 1.5 times the rated pressure, and the seat test pressure is 1.1 times the rated pressure, ensuring zero leakage.
Certification and Compliance
API 6D certification: It complies with the API 6D standard, ensuring product quality and performance.
Other certifications: Including ISO 9001, CE certification, SIL 3 functional safety level, etc.
Advantages
High-performance sealing: It provides 100% leak-free operation.
Low operating torque: Compared with traditional designs, the operating torque is reduced by 45%.
Customization service: It offers multiple customization options, including material selection, operation mode and special coatings.
Global compliance: It complies with international standards and is suitable for the global market.
