Tips for choosing a valve: You should be careful when choosing the valve that best suits your purpose. In order to avoid ambiguity, each valve should be accurately defined, the inquiry or order should be made on the required valve to give a full and appropriate description. 1, the valve control function is what? Each valve structure is used to perform some function. Do not expect a valve to perform all the functions of the entire piping system. 2, pressure - temperature rating. In order to meet the actual needs, pay special attention to the required valve pressure - temperature rating. Pay special attention to the sealing material and gasket material that 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. 3, the valve and connection. The integrity of the piping system, future routine maintenance, corrosion protection, on-site assembly, weight and safety, among other factors, all determine the factors that should be considered when connecting a valve to a pipe. 4, operation mode or method of operation According to the valve type, size, pressure, temperature, installation environment and other factors to choose the appropriate mode of operation or operation. 5, 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. 1) valve diameter. 2) Pressure Interface Materials: Castings and Parts Materials. 3) Valve Type: Imported valve ball valve needle valve, globe valve, gate valve, check valve, butterfly valve and so on. 4) Terminal connection method, if the connection method is welding method, but also to provide the pipe wall thickness of the connection pipe; If the connection is flange, to provide the flange surface or polishing degree. 5) Any material different from standard equipment: Sealing material, Precipitation material, Bolt material, etc. 6) any attachment: anti-acid protective layer, locking device, chain operation, and so on. 7) Manual or powered actuator: Please include the requested technical details. 8) For the convenience of ordering, please confirm the model number. The nominal diameter of the pipe connected to the valve must be determined. Valve Materials When determining the correct valve material, the following should be considered: • The fluid medium to be controlled by the valve; • The temperature range of the fluid medium; • The pressure range to be experienced by the valve; • The climatic conditions that may affect the valve's operation; Subject to possible abnormal pressure or stress; Safety standards or piping regulations to be met.
