Teach you how to order American valves
The United States valve known for its excellent quality, how to order the United States valve, this article in English and Chinese more intuitive way to teach you how to operate. We hope to help you choose the right valve for a wide range of piping environments. We offer a wide selection of valves for you to choose from. These valves in this network have a detailed description of the war. This catalog has been published to assist you in choosing the correct valve for a vast number of piping conditions. The Aloyco product line makes available to you a very broad choice of valves. These valves are described in this catalog. Use the valve should be careful. In order to avoid ambiguity, every valve should be accurately defined. When asking for a quote or ordering, a full and proper explanation of the valve required should be made. Care should be taken to select the most suitable valves for your service (s). Exact specification of each valve should be made to avoid possible ambiguity. When requesting quotations and / or ordering the product a fully adequate de & # 115; cription should be made Selecting the Valve Size Selecting the Valve Size You must determine the nominal size of the pipe to which the valve is connected. Valve material Valve Material When determining the correct valve material, the following factors should be considered: The following facts should be considered in determining the correct valve material: • Valve to be controlled The medium or media which will be controlled · the temperature range of the line medium (media) · the pressure range to which the valve will be subjected · the possible influence The possible climatic conditions in which the valve will be subjected to pressure or stress that may be experienced by the valve · Safety standards and piping regulations to be met · safety standards and / or piping codes Which valves must be met Type of Valve What is the control function of the valve? Each valve structure is used to perform some function. Do not expect a valve to perform all the functions of the entire piping system. Do not expect one type of valve to perform all the valving jobs in a system. Pressure-Temperature Ratings In order to meet the actual Need, please pay special attention to the pressure required for the valve - temperature rating. Pay special attention to the sealing material and gasket material, which to a large extent determine the pressure-temperature rating of the valve. According to the actual needs of the designated sealing material and precipitation materials to meet or better than the actual needs. Please pay careful attention that the pressure-temperature ratings of a particular valve are in keeping with the requirements of the service. Pay especially careful attention to the packing and gasket materials as this may limit the rating as is the case with PTFE used as the standard in Aloyco valves. Specify alternative packing and / or gasket materials as necessary to meet or exceed your service requirements. Valves and Connections Valve and Connections Pipeline System Integrity, Future Routine Maintenance, Corrosion Protection, Field Assembly, Weight and Safety And so are the factors that determine the valve and pipe connections should be taken into account. 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. Operating Modes or Operation Method of Operation Depending on valve type, size, pressure, temperature , Installation environment and other factors to choose the appropriate mode of operation or operation. When ordering the valve, please provide the following data to avoid unnecessary repetition and Delay to ensure that the valve purchased is indeed the valve you need. Please state the following information when ordering a valve in order to avoid unnecessary delays and to insure we supply you with the valve you have requested.
