Integral welded ball valve, no external leakage, etc.
Since the valve seat is composed of carbonized Teflon sealing ring and coffee spring, it has strong adaptability to the changes of pressure and temperature, and will not produce any slip within the marked pressure and temperature range.
The machining process of the sphere is tracked and detected by an advanced computer detector, so the machining accuracy of the sphere is high.
As the material of valve body is the same as that of pipeline, there will be no uneven stress, no deformation due to earthquake and vehicle passing through the ground, and the pipeline is resistant to aging.
The seal ring body is made of cptfe with a content of 25% carbon (carbon), ensuring no leakage (0%).
The directly buried welded ball valve can be directly buried underground without building a high and large valve well. It only needs to set a small shallow well on the ground, which greatly saves construction cost and engineering time.
The length of the valve body and the height of the valve stem can be adjusted according to the construction and design requirements of the pipeline.
The machining accuracy of the sphere is very precise, the operation is light, and there is no bad interference.
The use of advanced raw materials can ensure the pressure above PN25.
Compared with the products of the same specification in the same industry, the valve body is small and beautiful.
Under the condition of ensuring the normal operation and use of the valve, the warranty is 20 years.
