Product Description
MAIN FEATURES:The top-entry ball valve is designed as an integrated valve body. Its support and ball rod fixed by an upper-assembled pivot and an integrated pivot respectively and the integrated high-strength ball rod ensure an accurate ball positioning. The unique technology of retractable valve seat is adopted, realizing online replacement of valve stem, valve stem seal rings, metal valve seats and preloaded springs.
Design FeaturesThe ball valve are designed in accordance with ISO14313,API 6D,API608,BS 5351;
Simple structure with good tightness and small torque;
One piece type body;
Have reduce bore and full bore with the minimum flow resistance (zero actually);
Emergency sealant injection;
Cavity pressure self relief;
Low emission packing;
Fire safe, anti-static and anti-blowout stem design;
Valve seat function DBB, DIB-1, DIB-2;
Optional extended bonnet.
TOP ENTRY BALL VALVE is mainly used in pipeline and industry system and it has a top entry and on line maintenance function.It has a lot of advantages,such as small fluid resistance,simple structure,small volume,light weight,reliable saaling,convenience for operation and maintenance,open and close quickly,as well as start and close flexibly.
1.One piece bodyOne piece body is used for the body to guarantee sufficient strength and rigidity under maximum rated operating pressure.The internal parts of valve are carefully designed and selected to ensure reliability under all kinds of operating condition.Enough margin wall thckness and adaptation of high strength connective bolts are convenient for valve maitenance and sufficiency to support the stress from piping.
2.Top entryIts most difference from common ball valve is that its maintenance can be made on pipe line and without dismounting from the pipe line.The back space seat structure is adopted for the seat and the rear portion of seat retainer is oblique angle to prevent accumulation of impurity from affecting back space of seat.
3.Low operation torqueTop entry series ball valve has a trunnion mounted ball,whose surface is ground,polished and hard face treated.The ball and stem is integrated,sliding bearing is installed on the external bore so that the friction radius is small and operation torque is very low.
4.Emergency sealingCompound injection holes are designed and compound injection valves are installed at locations of stem/cap and body support of side valve.When sealing of stem or seat is damaged to induce leakage,the compound can be used to do the second time sealing.A concealed check valve is installed in side of each compound injection valve to prevent compound from out flowing due to the action of transmitter substance.The top of the compound injection valve is the connector for fast connection with compound injection gun.
5.Reliable sealingThe seat sealing is formed by seat sealing and metal retainer component.The seat retainer floats axially and low pressure sealing of valve seat is reached by pre-pressure of spring.In addition,the piston effect of valve seat is designed reasonably,which realized high pressure sealing by the pressure of operating medium and realize the interception of retainer to form the sealing of the body.The expansion graphite ring is designed to realize sealing under fire condition.
6.Double block&bleed(DBB)When ball is full open or close position,the transmitter substance in center cavity of body can be released by drainage and emptying devices.In addition,the over loaded pressure in the center cavity of valve can be released to low pressure end by self relief seat.
7.Anti-static and fire safe designThe fire prevention design of valve meets the requirement in API6FA/API607 standard and the design of the anti-static conforms to regulations in API6D and BS5351.
8.Extension stemFor the underground installed valve,the stem can be lengthened and for the convenience of operation the corresponding compound injection nozzle and drainage valve can be extended to the top of valve.
9.Various driving typesThe top pad of valve designed according to ISO 5211,which is convenient for connection and exchange of various drivers.The common driving types are manual,electrical,pneumatic and pneumatic/hydraulic.
