Ball Valve API 608
Rame API 608 Ball Valve
API 608 Floating Ball Valve
API 608 is a standard which exceeds the requirements set by ASME B16.34, thereby offering a superior level of performance for the rigorous requirements of the petrochemical, power, oil and gas and water treatment markets.
The API 608 range incorporates a number of useful features including increased thickness and oversized driving train. These characteristics, together with construction from high performance materials, make these valves ideal for severe and demanding environments and particularly reliable in actuation applications.
This standard establishes requirements for bore sizes described as:
- Full bore
- Single reduced bore
- Double reduced bore
API 608 ”specification for flanged, threaded and welded metal ball valves” provide detailed requirements for ball valves in terms of structural design, performance requirements, test methods and other aspects. API 608 a complete specification of ball valves in the petrochemical field, and each has its own characteristics according to different working conditions and requirements. API 608 adds the requirements like design, operation and performance based on ASME B16.34 “flanged, threaded and welded valves for general industrial use”.
Application and Structure
API 608 ball valve is used for the petrochemical industry pipeline media opening or cutting off, which is under the environment such as high temperature and high pressure, inflammable and explosive, corrosive and continuous operation, where require more requirements on valve sealing, material, corrosion. API 608 ball valve has a fixed ball structure and floating ball structure and mainly floating ball structure.
Inspection and Testing
API 608 provides for the inspection, inspection and pressure testing of ball valves in accordance with API 598” inspection and testing of valves”. As a supplement to ASME B16.34, API 608 ball valves shall also fully meet ASME B16.34” inspection and test requirements”. ASME B16.34 and API 598 are basic specifications for general purpose valve.
Installation and Maintenance
API 608 ball valves can be installed in the factory, easy to store and transport. API 608 ball valve to ensure long-term safe and reliable operation of the long-distance pipeline. API 608 ball valves are used in petroleum, petrochemical and industrial applications, mainly for ASME B31.3 process pipeline, diameter range NPS (1/4 ~ 24), small diameter, pressure class 150, 300, 600, 800 pounds, generally floating ball structure, sealed at the outlet.
