Frequently Ask Questions
It is a ball valve designed for maintenance access from the top of the valve body without removing the complete valve from the pipeline.
Full Bore is preferred where low pressure drop and pipeline pigging requirements are important. Reduced Bore may be selected where compact size, weight or cost is a consideration.
Higher differential pressure increases the load acting on the ball and seat, so the seat design and material must be selected according to pressure, temperature and process medium.
The difference is how the seat responds to pressure from the pipeline and valve cavity. The required configuration depends on the isolation and pressure-relief requirements.
The selection depends on the valve seat design, pressure-relief philosophy and project specification. The manufacturer should confirm the applicable configuration.
Actuator sizing considers breakaway, running and seating torque, maximum differential pressure, seat design, temperature and an appropriate safety margin.
It allows inspection and maintenance of internal components from the top, which can be useful for pipeline installations where valve removal is difficult.
Soft seats are generally selected for tight shut-off in compatible services, while metal seats may be required for higher-temperature, abrasive or demanding applications.
A blowout-proof stem is designed to prevent stem ejection from the valve body under internal pressure, improving operational safety.
Cavity relief is used to manage pressure that may become trapped inside the valve body cavity when the ball is in the closed position.
API 6D provides requirements relevant to pipeline and piping valves, including applicable design, manufacturing, testing and documentation requirements.
