How to specify and order the correct valve? 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. Use caution when choosing the valve that best suits your purpose. In order to avoid ambiguity, every valve should be accurately defined. When inquiring or ordering, a full and proper explanation of the valve required should be made. Select the valve diameter must determine the nominal diameter of the pipe connected to the valve. Valve Materials When deciding on the correct valve material, the following factors should be considered: • The fluid medium to be controlled by the valve • The temperature range of the fluid medium • The range of pressures to be subjected to the valve • The climatic conditions that may affect the valve's operation • The valve to be subjected to, possibly Abnormal pressure or stress · Safety standards to be met or pipeline regulations Valve category 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. Pressure - Temperature Ratings To meet your exact needs, pay special attention to the pressure - temperature rating of your valve. 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. Valves and Connections Pipeline integrity, future routine maintenance, corrosion protection, site assembly, weight and safety all determine the factors valve and pipe connections should consider. Mode of operation 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. Ordering of Valves When ordering a valve, please provide the following data to avoid unnecessary repetition and delay to ensure that the valve purchased is indeed the one you need. 1. Valve Path 2. Pressure Interface Materials: Castings and Parts Materials. 3. Valve types: gate valve, globe valve, check valve, butterfly valve, ball valve, and so on. 4. Terminal connection, if the connection method is welding, but also to provide pipe wall thickness of the connection pipe; If the connection is the flange, to provide the flange surface or polishing. 5. Any material different from the standard configuration: Sealing material, Precipitation material, Bolt material, and so on. 6. any accessories: anti-acid protective layer, locking device, chain operation, and so on. 7. Manual or powered actuator: Please include the requested technical details. 8. For ordering convenience, please confirm the model number.
Surfacing hardness is 63 degrees; it still has high wear resistance in high temperature working conditions of 500 °-° 600 °, and the tempering hardness HRC63 remains unchanged. The wear resistance is 20-25 times that of low carbon steel, 5-10 times that of stainless steel and high manganese steel, and 1.5 times that of general high carbon high chromium wear-resistant steel plates. It can be curled, and it can be curled with different curvatures according to the thickness of the motherboard.
