This butterfly valve is suitable to temperature≤80?C,is used on petroleum，chemical industry foodstuff medicine gently the spinning and papermaking，power，plumbing and gas pipe route,and does the effect adjusted the volume of flow and dams a river the medium. Possess the bloated cold function that contracts of compensation pipeline heat.
特点
1、设计新颖、合理、结构独特、重量轻、操作方便、起闭迅速。
2、本伸缩蝶阀既能起到调节流量和截流作用，又能补偿管道温差所产生的热胀冷缩功能，同时也便于安装和拆卸，为一阀多用产品。
1.The design is new and original and reasonable and the structure is unique and is light in weight and operates makes things convenient for and it is rapid case to close.
2.This stretch butterfly valve can act to adjust the volume of flow with damming a river the effect，to compensate that the pipeline difference in temperature is given rise to again hot expands to cool contracts the function，and but also being easy to at the same time install and dismanteles，uses the product for one valve more.
