API 6D ball valve Class 300 Carbon Steel A216 Wcb API6d Standard Flanged China factory
What's the API6D ball valve ?
When it comes to the body style, ball valves can often be divided into side entry ball valve, top entry ball valve and fully welded ball valve.
API6D ball valve is the valve that assembled its ball from top side part. It just like a globe valve that has body and bonnet except the trim part utilize a ball type. It comprises one single body. Top entry ball valves are used in piping systems where the top of the valve can be removed to gain access to the ball and seats without removing the entire valve from the piping system. Top entry ball valves are typically used in process systems where in-line maintenance is preferred over full valve removal. Therefore it’s very common to use top entry ball valves at high pressure application that require in-frequent maintenances such as HIPPS (High Integrity Pressure Protection System) valves etc. The advantages of the top entry ball valves is its construction that allow minimal thread connection so that it will also minimize possible leak path.
It is possible to remove the bonnet of the API6D ball valve allowing free access to the body cavity without dismantling the valve from the line. A set of special maintenance tools permits to take out both ball and seat-rings; this maintenance operation requires very little space around the valve, thus allowing it in areas where space is a limiting factor.
