Be careful to choose the valve that best suits your needs. At present, the valves produced by various valve manufacturers have strict specifications. Therefore, the purchaser should make a comprehensive and appropriate description of the required valve when inquiring or ordering.
The selected valve diameter must determine the nominal diameter of the pipe connected to the valve. When determining the appropriate valve material for the wastewater solenoid valve, the following factors should be considered:
The type of fluid medium to be controlled by the valve.
The second is the temperature range of the fluid medium.
The third is the pressure range that the valve should withstand.
The climatic conditions that may affect the valve operation.
The possible abnormal pressure or stress that the valve should withstand.
6. Safety standards or piping specifications that should be met.
Valve control function. Each valve structure is used to perform certain functions, do not expect a valve to complete all functions in the entire pipeline system. In addition, in order to meet actual needs, special attention should be paid to the rated pressure and temperature of the required valve. Special attention should be paid to the sealing materials and gasket materials, which largely determine the rated pressure and temperature of the valve. Specify sealing materials and precipitation materials as required to meet or exceed the actual requirements of hydraulic solenoid valves.
Valves and connection methods. The integrity of the pipeline, daily maintenance, anti-corrosion factors, on-site installation, weight and safety are all factors that should be considered when determining the connection between the valve and the pipeline. The operation mode or method should be selected according to the valve type, size, pressure, temperature, installation environment and other factors.
Therefore, when purchasing a valve, please provide the following data to avoid unnecessary duplication and delay, and to ensure that the valve you purchase is indeed what you need.
One is the diameter of the valve.
Pressure interface materials: castings and parts materials;
Valve type: gate valve, globe valve, check valve, butterfly valve, ball valve, etc.
For the end connection method, if the welding method is adopted, the thickness of the pipe wall of the connecting pipeline shall be provided; if the flange type is adopted, the flange surface or the degree of polishing shall be provided.
