Welded ball valve

Welded ball valve refers to the connection method between ball valve and pipeline using welding, mainly including butt welding and socket welding. It is generally suitable for ultra-high pressure pipeline equipment or pipelines and equipment with limited installation space. The main characteristics of welded ball valve are fixed connection points, low leakage, and easy maintenance. The opening and closing components (ball) of the welded ball valve are driven by the valve stem to rotate 90 degrees, thereby achieving the smooth or closed operation of the valve. The integrated welded ball valve produced by Shanghai Meiyan Yi Pump Valve is particularly suitable for steam heating pipelines. The product has stable performance, light weight, and superior sealing performance. It adopts an integrated welded valve body structure and a valve seat composed of PTFE sealing rings and springs, with strong adaptability to pressure and temperature changes and no leakage.
