The selection of
solenoid valve connector should first follow the four principles of safety, reliability, applicability and economy, and then be selected according to the site working conditions in six aspects (i.e. pipeline parameters, fluid parameters, pressure parameters, electrical parameters, action mode and special requirements).
Selection basis of
the DIN valve connector
1. Select the solenoid valve according to the pipeline parameters: diameter specification (i.e. DN) and interface mode
1) Determine the diameter (DN) according to the internal diameter size or flow requirements of the on-site pipeline;
2) Interface mode: generally, flange interface shall be selected if it is > DN50, and it can be freely selected if it is ≤ DN50.
2. Select the material and temperature group of the solenoid valve according to the fluid parameters
（DIN valve connector)
1) Corrosive fluid: corrosion resistant solenoid valve and all stainless steel should be selected; Edible ultra clean fluid: food grade stainless steel solenoid valve should be selected;
2) High temperature fluid: the solenoid valve made of high temperature resistant electrical materials and sealing materials shall be selected, and the piston structure type shall be selected;
3) Fluid state: it must be distinguished from gas state, liquid state or mixed state, especially when the diameter is greater than DN25;
4) Fluid viscosity: generally, it can be arbitrarily selected below 50cst. If it exceeds this value, the high viscosity solenoid valve shall be selected.
