Several parameters of the standard of electromagnetic valve type selection

Solenoid valve solenoid valve belong to several parameters selection standard times industrial automation is the basis of the components of an actuator, is mainly used to control the direction of hydraulic flow, isolation equipment and piping system, regulating flow, preventing backflow, and discharge pressure. In the pneumatic system, the role of the solenoid valve is according to the requirements of control in the control system to adjust the various states of compressed air, as is used to control the solenoid valve in the pipeline control plays a key role. So how to selection of solenoid valve, the following is several reference index of solenoid valve type selection. According to the fluid to select the material of solenoid valve, temperature parameters of corrosive fluids appropriate chooses corrosion-resistant solenoid valve and all stainless steel; Consumption of super clean fluid appropriate chooses food grade stainless steel solenoid valve. High temperature fluid should choose to use high temperature resistant electric solenoid valve materials and seal materials, and to choose the piston structure type. Fluid state to a gaseous, liquid or mixed state, especially the diameter greater than the DN must distinguish when you order it. Fluid viscosity under cSt usually can be arbitrary choice, if more than this value, should choose high viscosity solenoid valve. According to the varieties of pressure parameter selection principle and structure of electromagnetic valve nominal pressure the meaning of this parameter with other general valve is the same, is set according to the pipe nominal pressure. Working pressure if low working pressure must be selected or step by step of moving straight acting principle; When the minimum working pressure difference, Mpa above straight acting, step by step straight acting, guiding type all can choose. Electrical select voltage specifications should be preferred as far as possible choose ACV, DC listed is more convenient. According to the continuous working time length to select the normally closed, normally open, or sustainable electricity when the electromagnetic valve, need long time to open and close the time duration of excess type should be chosen normally open. If you open the short time or a little while, and off time is normally closed type chosen. But there are some conditions for security protection, such as furnace, furnace flame monitoring, cannot choose normally open, choose the long-term operation. According to the environmental requirements to assist explosion-proof, check, manual, waterproof, water spray mist, diving explosive environment must choose corresponding explosion-proof grade of solenoid valve solenoid valve factory is a national high-tech enterprise, the production of various series solenoid valve belongs to high-tech products.
