• metal seated ball valves, high pressure ball valves Cast steel metal seated ball valve Description The seat 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.
