АОГ электрический шаровой кран фланец

AOX electric flange ball valve feature Small fulid resistance,the fluid resistance of ball valve(including reduced ball valve) is the most least among valves.Valve stem operate flexibly for long term as the thrust bearing reduces the friction torque of valve stem.Well sealing for valve seat,with PTFE material gasket ring ,easy to seal,moreover,the sealing performance of ball valve raises along with the increase of medium pressure.Reliable sealing performance of valve stem,the stuffing sealing of valve stem is not easily to be destroyed ,as the valve stem only do rotary motion,but not heaving motion,more,the sealing performance raises along with the increase of medium pressure.Well self-lubricating peoperty for PTFE,little friction loss with valve body,so,long life of ball valve.The valve stem and the stem head installed from bottom of sleeve,prevent valve stem from blowing out,for example, fire will destory the sealing of the valve stem,but the stem head has metalic contact with the valve body,to ensure the sealing performance of the valve stem.
