API 6D,ISO 17292 Top-entry ball valve F304 F316 R-PTFE SEAT 300LB
The top entry ball valve is mainly used on pipelines and industrial systems. It has such advantages as top online maintenance function, small fluid resistance, simple structure, reliable sealing, convenient operation and maintenance, rapid on-off operation, flexible opening and closing, etc. The driving modes include manual operation, worm and worm gear transmission, pneumatic operation and electric operation. The connection ends can be flange or butt welding.
1. Integral structure
The body adopts the integral structure, so as to ensure that it has enough strength and rigidity under the maximum rated working pressure. The valve trims have been carefully designed and selected to ensure reliability under various service conditions. The sufficient wall thickness and the connection bolts of high strength are very helpful to the maintenance and servicing of valves and are able to endure pipelines stress.
2. Top Entry Structure
The vale adopts the top entry structure. The most distinctive difference between this kind of valve and others is that the online maintenance function can be realized without the need of removing the valve from the pipeline. The seat adopts the concession type seat structure, and the rear end of the seat retainer is set as oblique angle to prevent impurities accumulated on the seat from influencing the concession of seat.
Use of forgings and the independent spring or bellows loaded floating seats which are always in contact with the ball make these valves the preferred solution for various critical applications like cryogenic, high temperature, low emission, Emergency Shutdown (ESD) or High Integrity Pressure Protectors (HIPPS) systems and sub-sea.
