、产品结构特点Structural characteristics of the product：
1.上装式结构。对装在管路上的阀门可直接在管路上检查与维修，减少停车时间提高效益。
2.使用寿命长。中法兰选用抗张、抗压的金属垫片增强抗温，耐腐蚀性能有效延长使用寿命。
3.防止误操作。开关带锁定装置有效防止误操作，确保阀门处于正确位置。
1 coat structure. Installed in the pipeline for the valve directly in the pipeline inspection and maintenance, decrease downtime and improve efficiency.
2 long life. Flanges used in the tensile, compressive resistance of the metal gasket enhanced temperature resistance, corrosion can effectively extend the service life.
3 to prevent misuse. Switch with an effective locking device to prevent misuse and ensure the valve is in the correct position.
