Q341F all welded ball valve
Uses: City gas: gas output pipeline, main line and a branch supply pipeline.
Central heating: large heating equipment output pipeline, main line, branch line.
Heat exchanger: Pipes and circuits open and close.
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.
Features: One-piece welded ball valve, no external leakage.
Q347F all-welded ball valve is made of carbon fiber reinforced Teflon seal and butterfly spring. It has strong adaptability to pressure and temperature changes and will cause any leakage inside the marked pressure and temperature range. The processing of the sphere is tracked and detected by an advanced computer detector, so the processing of the sphere is accurate and 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 body is made of RPTFE with 20% carbon (carbon) to ensure complete leak-free (0%). The direct-buried welded ball valve can be directly buried and underground. 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 construction and design requirements. The machining accuracy of the ball is very precise, the operation is light and there is no adverse interference. The use of advanced raw materials guarantees pressure above PN25. Compared with similar products of the same industry, the valve body is small and beautiful in appearance. The service life is more than 15 years under the condition of ensuring normal operation and use of the valve.
Installation: All ends of the steel ball valve are welded by electric welding or by hand. The valve chamber should be protected from overheating. The distance between the solder ends should not be too short to ensure that the heat generated by the soldering process does not damage the sealing material. The valve should be fully open during installation.
