Product Details

Applications

API6D High-performance pipeline ball valve is Raymond(RMD)hightech products,as switch control equipment,it is mainly used in natural gas,oil,gas,liquefied natural gas pipeline transmission system and other industries,its anti-sulfur products containing hydrogen sulphide,impurities and high corrosion are suitable for the long-distance natural gas pipeline.
Main features

Body of high-performance pipeline ball valve is forged structure.The connection type for body and vice-body can be BB(bolted connection)and WB(welded connection).The WB(welded connection)and the LWB(Fully-welded extended stem)structure isadopted for buried ball valves,as shown below.
High performance pipeline ball valve series has the feature of strength,high perfect sealing,maintenance-free,long life and so on.The production of this series ball valve adopts the international advanced ball valve design and manufacturing technology,selects high-quality materials in accordance with the standard selection of materials and combines with advanced materials forming forging technology.At the same time,with the years of ball valve design and manufacturing experience,the use of advanced processing and manufacturing equipment and production and processing technology,through the first-class inspection and testing equipment and instruments,perfect quality assurance management system and excellence in the production of high-performance philosophy can ensure the quality of valves.This series of valve has the performance of a high strength,defect-free forging body,excellent sealing performance,even at maximum pressure difference(full pressure),it will still be able to ensure that seal without leakage,after frequent switching action to realize a safe usage in the transportation of oil,natural gas,coal gas,and other special medium transportation pipeline.

The special structure of valve seat seal

Floating structure means seat reciprocally can move along channel direction,so as to guarantee the ball and seat are tightly sealed.
(1)Valve seat structure suitable for different occasions and sealing requirements
Valve seat can be designed as a standard single-piston effect and specific dual piston effect,Figure1 shows single-piston effect-inletside seal;Figure2 shows Dual Piston effect-outlet-side seal;Figure3 shows special dual piston effect sealing structure
(2)Multi-level structure of the valve seat seal
As shown in Figure4,there are two elastic O-ring in the valve seat ring-ring A and ring B.Sealing ring A spring-loaded through the valve seat so that the sealing surface of sealing ring A tightly fit with ball surface to form an initial seal.When there is pressure in the system medium,the piston force
produced by the piston force produced by the piston effect of size difference makes elastic deformation of the ring A Ershi sealing surface and ball more closely fit the surface to form a re-sealing;meanwhile.
