Handle fully welded ball valve free-valve's handle fully welded ball valve are widely used in almost all the industry .compared to the general casting ball valve, fully welded ball valve have a highly performance and longer life time . It was widely used in city gas , city heat supply , oil chemical industry, ship building , steel , power plant etc . Fully welded ball valve can be reliable run in the long time , easy to be installed and less maintenance work . Benefits 1.valve body material is the same as the pipe material , so they will not occur transformation due to unbalanced stress . 2.face to face dimensions can be made according to customer requirement. 3.material of valve seat is made up of ptfe+20%c sealing ring and metal sealing , which can adapt to the change of pressure and temperature, so the leakage will not occur during the pressure and temperature range. 4.the ball body has a highly machining precision due to the tracking of computer detector, so the ball valve was shut offshut on conveniently. Valve specification type : FRQ61FC, FRQ361FC size range:NPS2NPS48 , DN50 DN1200 pressure range :Class150Class600, 1.6Mpa4.0Mpa material of valve body: A105, F304, F316 connect method :welding work temperature:-29-180 degree Celsius design standard:ASME B16.34, API6D test and inspect:API598 face to face:ASME B16.10 medium :water , oil , gas , acid , alkaili etc driving method : electric , handle, worm gear etc . Application industry: centralized heating, coal gas pipe, waste gas treatment system, heat supply system
