Fully welded ball valve

FREE-Valve’s 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 off/shut on conveniently. Valve Specification Type : FRQ61FC,FRQ361FC Size Range:NPS2~NPS48 , DN50 ~DN1200 Pressure Range :Class150~Class600,1.6MPa~4.0MPa Material of valve body: A105,F304,F316 Connect Method :welding Work Temperature:-29℃≤t≤180 ℃ 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.
