The JOEPAI high quality Lever Operated Fully Welded Ball Valve is composed of a carbonized PTFE sealing ring and a disc spring, and is used as a fully open and fully closed opening and closing device. Therefore, it has strong adaptability to changes in pressure and temperature, and will not produce any leakage within the marked pressure and temperature range.
Lever Operated Fully Welded Ball Valve, There will be no external leakage or
other phenomena.
The machining process of the sphere is tracked and detected by advanced
computer detectors, so the machining accuracy of the sphere is high.
Due to the fact that the valve body material is the same as the pipeline
material, there will be no uneven stress, and there will be no deformation
due to earthquakes or vehicles passing through the ground. The pipeline is
resistant to aging.
The sealing ring body is made of RPTFE material with a carbon content of
25%, ensuring complete leak free (0%).
Directly buried welded ball valves can be buried underground without the
need to build large valve wells. Only small shallow wells need to be set up
on the ground, greatly saving construction costs and project 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 accuracy of the sphere is very precise, the operation is
easy, and there is no adverse interference.
Using advanced raw materials, it can maintain a pressure of PN25 or
higher.
Compared with products of the same specifications in the same industry, the
valve body is small and has a beautiful appearance.
The service life of the valve is over 20 years while ensuring normal
operation and use.
