Advantages of all-welded ball valve:
全焊接球阀的优点：
The seat consists of a carbon fiber reinforced Teflon ring and dish spring, which does not slide in the displayed pressure and temperature range and is highly adaptable to pressure and temperature changes.
阀座由碳纤维增强特氟隆密封圈和碟形弹簧组成，在显示压力和温度范围内不发生滑动，对压力和温度变化适应能力强。
The ball processing process has advanced computer detector tracking detection, so the ball processing precision is high.
球体加工过程中有先进的计算机检测仪跟踪检测，因此球体加工精度高。
The body material is the same as the pipe material, no uneven stress, earthquake and vehicle through the ground will not be deformed, durable pipe.
阀体材质与管道材质相同，无应力不均，地震和车辆通过地面时不会变形，管道耐用。
