Note solenoid valve six site conditions

(Ie pipeline parameters, fluid parameters, pressure parameters, electrical parameters, action, special requirements).
Selection based on:pneumatic fitting
1, according to the pipe parameters: diameter of the solenoid valve specifications (DN) interface mode
1, in accordance to the the on-site inside diameter of the pipe size or the flow requirements to determine the the size of the (DN)-pass diameter.
2, interface mode, general> DN50 To select flange interface, ≤ DN50 freedom of choice can be based on user needs.
2 selected based on the parameters of the fluid material, temperature group of the solenoid valve:
1, corrosive fluid: better to use-resistant the corrosion solenoid valve and full-stainless steel; the consumption of ultra-clean fluid: better to use food grade stainless steel Material solenoid valve.
2, the high temperature fluid: To select the use of high temperature electrical materials and sealing materials manufactured solenoid valve the piston structure type, but also to select.
Fluid state: large gaseous, liquid or mixed state, especially when the diameter is greater than DN25 order must distinguish.
4, the viscosity of the fluid: usually 50cSt arbitrary choice, more than this value, will have to use the high viscosity of the solenoid valve.
Select solenoid valve 3, according to the pressure parameters: The principle and structure of varieties
1, Nominal pressure: this parameter together with the the meaning of of other General purpose industrial valves - is the same as, is according to the pipeline Nominal pressure to be,.
2, the working pressure: If the working pressure is low you must selection of direct-acting type principle of the direct-acting or sub-step-by-step; the minimum working pressure is in the the more than 0.04Mpa when direct-acting, step-by-step direct-acting, the Pilot-operated can be selected.electric solenoid valve
