Characteristic
There will be no external leakage or other phenomena between the integrated welding balls.
Due to the fact that the valve seat is composed of carbon fiber reinforced Teflon sealing rings and butterfly springs,it has strong adaptability to pressure and temperature changes and will not produce any leakage within the marked pressure and temperature range.The processing process of the sphere has advanced computer detectors and comprehensive detection,so the machining accuracy of the sphere is high.Due to the fact that the valve body material,like the pipe material,does not exhibit uneven stress,nor does t deform due to earthquakes or vehicles passing through the ground,the pipeline is resistant to aging.The sealing ring body is made of RPTFE material containing 20%Carbon,ensuring zero leakage. Directly buried welded ballvalves can be directly buried underground,without the need to build large valve wells. Only smallshallow wells need to be installed on the ground, greatly saving construction costs and 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,with easy operation and no adverse interference. Using advanced raw materials,it can withstand pressures above PN25.Compared with products of the same specification in the same industry,the valve body is small and has a beautiful appearance.The service life of the valve is longer while ensuring its normal operation and use.
Install
The end welding of allsteel ball valves adopts electric welding or manual welding to avoid overheating of the valve chamber.The distance between the welding ends should not be too short to ensure that the heat generated during the welding process does not damage the sealing material. During installation,allvalves should be opened.
