Since the seat is made of a carbonized Teflon seal ring and a disc spring, it is highly adaptable to changes in pressure and temperature, and does not cause any slippage in the marked pressure and temperature range.
structure
City gas: gas output pipelines, main lines and supply lines for each branch line.
Central heating: large heating equipment output pipeline, main line, branch line.
Heat exchanger: The pipeline and each circuit are opened and closed.
Steel plants: various fluid pipelines, exhaust gas pipelines, gas and heat supply pipelines, fuel supply pipelines.
Various industrial equipment: various heat treatment pipes, various industrial gas and heat pipes.
characteristic:
All welded ball valves will not have external leakage.
The processing of the sphere is tracked and detected by an advanced computer detector, so the processing accuracy of the sphere is high.
Since the valve body material is the same as the pipe material, there will be no uneven stress, and it will not be deformed due to earthquakes and vehicles passing through the ground. The pipe is resistant to aging.
The seal ring body is made of RPTFE with 25% Carbon (carbon) to ensure complete leak-free (0%).
The direct-buried welded ball valve can be directly buried in the ground. It is not necessary to build a large valve well. It is only necessary to set up a small shallow well on the ground, which greatly saves construction costs 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 processing precision of the sphere is very precise, the operation is light, and there is no adverse interference.
Using advanced raw materials, it can maintain pressure above PN25.
Compared with the same specification products of the same industry, the valve body is small and the appearance is beautiful.
The service life is more than 15 years under the condition of ensuring normal operation and use of the valve.
