Integrated fully welded ball valve overview:
Integrated fully welded ball valve is widely used in various fields. Its superior quality and high-performance stability cannot be achieved by ordinary cast steel ball valves. The integrated welded ball valve is suitable for media: oil, gasoline, liquefied natural gas, liquefied petroleum gas, petrochemical industry, steel plants, heating pipelines, etc. The service life is much longer than that of cast steel ball valves.
Technical features of one-piece fully welded ball valve:
The valve body structure is integrally welded and there will be no external leakage.
The valve seat is composed of a sealing ring and a spring and has strong adaptability to changes in pressure and temperature, and will not cause any leakage within the range of use.
, Anti-leakage structure of the valve stem. There is a self-sealing sealing gasket and a shaped sealing ring at the bottom of the valve stem. There is a shaped sealing ring and two sealing rings on the top to ensure no leakage.
The valve body material is the same as the pipe material, so there will be no uneven stress, nor will it be extruded and deformed due to earthquakes and vehicles passing over the ground.
The valve body is light and easy to keep warm.
. Directly buried ball valves can be buried directly underground. There is no need to build tall valve wells. Instead, only small shallow wells are needed 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 accuracy of the sphere is very precise, the operation is light, and there is no adverse interference.
There are two connection methods: welding and flange.
, Operation mode: handle, gear (vertical/horizontal)
, Under normal operation and use of the valve, the warranty period is one year.
