Note:
1.All of our butterfly valves are backed by 24 months guarantee.
2.We can match the different rubber ring according to the different medium conditions, such as NBR ,PTFE, CSM, EPDM, CR,Viton and other rubber materials.
3.We can match different materials about body, plate and stem, such as ductile iron, cast steel, stainless steel 304,316,316L according to special working condition.
4.If the valve leakage after two years service, just remove handle then add a bushing to prevent leakage
