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. 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.

We are offering forged steel metal seated ball valve. material of general purpose ball valve employs generally non-metal material, such as ptfe. Limited by the seat material, the general purpose ball valve can not be used in case of high temperature application, and application medium with solid articles, and ash dregs neither. So, the application scope of general purpose ball valve is restricted partially. Taking this into consideration, our company has developed successfully after years of hard study full range of metal to metal sealed ball valve, including floating ball valve and trunnion ball valve, which have found extensive applications in such industries as petroleum, chemistry, power, metallurgy, and light industry. purpose metal to metal ball valve of class 150-class 2500, pn 16- pn 160, jis 10k- jis 20k are applicable to various pipeline and use to truncation and get through of the medium. That should be according to select different material for use while being different kinds of medium, that can be applied to non-corrosive medium, weak corrosion medium, nitric acid, acetic acid, oxidizing medium, urea and other medias; especially suitable for containing solid particles medium, slurry, powder coal, ash and other harsh work condition. The operation including, manual, gear box, pneumatic actuator, electric actuator and hydraulic actuator. Metal to metal ball valve is now available for flange ends, and also can use bw ends, sw ends, npt ends and wafer ends. advanced hardening technology employed for ball and seat metal to metal sealed design has been employed perfectly for the ball and seat, which has also adopted the advanced hardening technologies, such as ultro-sonic spray coating, nickel base spray welding, surface specially hardening, stellite spray welding, ceramic material with high strength and hardness, and so on. Surface hardness of the ball and seat may generally reach more than hrc60, maximun is up to hrc74, and application temperature of the material may be up to 540, maximun is 980. Combining strength of the material gets to more than 10000 psi. Besides, the surface materials posses also very good resistance properties of friction and impact. Metal to metal sealed ball valves made by sedelon are suitable for use in most criticle working conditions. standards and specification design & manufactureapi 6dapi 608asme b16.34ansiawwa c507mss sp-72bs 5351bs 6364bfci 70-2iso 5211nace mr0175 . connection endsasme b16.5asme b16.47api 605mss sp-44iso 7005-1jis b2238bs 12627asme b16.25asme b16.11bs 12760 . face to face dimensionasme b16.10iso 5752bs 558bs 12982 testing & inspectionapi 598api 6dapi 607api 6fabs 6755bs 12569mss sp-82mss sp-61 normal pressure or ratingclass 150 class 2500jis 10k 20kpn 10 pn 420normal diameter or borenps1/2nps10dn15dn250applicable temperature-196540operation typemanual, worm gear, pneumatic, electric forged steel metal seated ball valve , high pressure ball valves

There are two kinds of applications for v type ball valve according to customers?? different requirement. One is used for cutting off or switch on the pipeline medium. The other is used as control valve for regulating the medium flowcapacity in pipeline. Operation manners for cutting off type ball valve include manual, worm gear, pneumatic or electric actuators, where as for regulating type v type ball valve, open ball valve, open manners are of pneumatic and electric actuators. Of the application for metal sealed v type ball valve, the temperature is in general 200 .as specially ordering, the application temperature for metal to metalsealed v type ball valve can be 425 (carbon steel valve body) or 540 (valve body of stainless steel, crmo steel, and crmo v steel).for soft sealed v type ballvalve, the application temperature is in general 180(reinforced ptfe seat). Connection type for v type ball valve is of water flanged connectionfeatures1. For v type ball valve, the bevelling spring or pillar spring loaded movable seat design has been employed, which is reliable in seal and of long service life asthere in no such problems as clenching or disjointing. 2. It features the function of slipping between the ball with cutting edge and metal seat, which is particularly suitable for the medium containing fibre, solid particles, thick fluid, and so on. 3. As per different working conditions of customers, several kinds of advanced techniques have been employed separately for the ball and seat surface of metal to meta l sealed ball valve, such as nickel base alloy by spraying welding (for hardness hrc60), stellite alloy by ultra-sonic spraying coating (for max. Hardness ?rc70), and specially hardened material etc. , which are suitable for many kinds of critical working conditions. 4. When the valve is fully open, flow capacity is big, pressure loss is small, and the medium would not deposit in the body cavity. 5. Being impact in structure and extensive in common use, the cutting off v type ball valve features perfect sealing property and may replace gate valve, globevalve and general ball valve. For regulating v type ball valve, its regulating scope available is wide, and its regulating accuracy is high.
