Description

Cast Iron Flange Stop Valves are commonly used shut-off valves, which are mainly used to cut off the medium in the pipeline, and are generally not used to adjust the flow. This product is suitable for a wide range of pressure and temperature, but is generally used for small and medium-diameter pipes. Compared with the gate valve, the structure of the globe valve is simpler, and the manufacture and maintenance are more convenient. Its sealing surface is not easy to be worn and scratched, so the sealing performance is better. The product is widely used in water supply and drainage, gas, electricity, metallurgy, petroleum, chemical, textile and urban construction industries.


Features

1 The Cast Iron Flange Stop Valves have a simple structure, so they are more convenient to manufacture and maintain.

2 The product has a small working stroke and a short opening and closing time.
