HAPPY NEWR YEAR 2012! Near 15 years, the metal sealed ball valve used widely and squeezed by the Chinese high-speed, continuous and stable development of industrialization in the country's medium-term. On the one hand, show a strong demand for machinery and equipment; made to revitalize the equipment manufacturing industry and strategic objectives.
For the inspection, please be aware some of customers that they will ask their inspection company to attend all the tests which will be done to the valves especially the hydrostatic tests. As a professional manufacturer, we should supply all documents likely materials test report, hydraulic pressure testing report and so on. And the pressure testing report will be made according to API 598 if the valves are designed according to ANSI/API standard. The testing standard indicates the leakages level for different valves. The testing includes backseat Test, shell test, low-pressure closure test and high-pressure closure test.
The below table is a ball valve enquiry from our customer. It is a sample. And it is no need to inform full information, but please try to inform the working situation so that we can make the choice. And please pay attention as below:
Valve Size : Nominal size of the pipeline into which the valve will be placed must be determined. Valve Material : The facts should be considered in determining the correct valve material, likely the medium, temperature range, pressure range, possible atmospheric conditions and extraordinary stresses, safety standards and or piping code etc. Valve Type : What is the control function of the valve? Gate valve, globe valve, check valve, ball valve, butterfly valve, plug valve etc. Pressure-Temperature Ratings : Please pay careful attention that the pressure-temperature ratings of a particular valve are in keeping with the requirements of the service. Also please pay attention to the packing and gasket materials as necessary to meet or exceed your service requirements. Valve and Connections : Considerations as to pipeline integrity, future maintenance, corrosion factors, field assembly, weight and safety should be given in determining the method of connecting the valve in the pipeline. Method of Operation : The means by which the valve is operated as supplied are shown for the valves in this catalog. Many optional operating devices are regularly supplied by us. Talking about the valve trim, the internal elements of a valve are collectively referred to as the valve trim. The trim typically includes a disk, seat, stem, and sleeves needed to guide the stem. A valve performance is determined by the disk and seat interface and the relation of the disk position to the seat. Because of the trim, basic motions and flow control are possible. In rotational motion trim designs, the disk slides closely past the seat to produce a change in flow opening. In linear motion trim designs, the disk lifts perpendicularly away from the seat so that an annular orifice appears.
