Product Description

Selection basis Solenoid valve selection should first follow the four major principles of safety, reliability, applicability and economy, followed by the selection of six field conditions (namely pipeline parameters, fluid parameters, pressure parameters, electrical parameters, mode of action, and special requirements).Selection basis:1, according to the pipeline parameters to select the solenoid valve: diameter specifications (i.e. DN), interface mode1) Determine the diameter (DN) size according to the internal diameter size or flow requirements of the pipeline on site;2) Interface mode, generally >DN50 to choose the flange interface, ≤DN50 can be free to choose according to user needs.2, according to the fluid parameters to select the solenoid valve: material, temperature group1) Corrosive fluids: corrosion-resistant solenoid valves and all stainless steel should be selected; Food ultra-clean fluid: food grade stainless steel solenoid valve should be selected;2) High temperature fluid: to choose the solenoid valve made of high temperature resistant electrical materials and sealing materials, and to choose the type of piston structure;3) Fluid state: large to gaseous, liquid or mixed state, especially when the caliber is greater than DN25 must be distinguished;4) Fluid viscosity: usually below 50cSt can be arbitrarily selected, if more than this value, you should choose a high-viscosity solenoid valve.

3, according to the pressure parameters to select the solenoid valve: principle and structural varieties1) Nominal pressure: This parameter has the same meaning as other general valves, and is determined according to the nominal pressure of the pipeline;2) Working pressure: If the working pressure is low, direct action or step by step principle must be selected; When the minimum working pressure difference is above 0.04Mpa, direct acting type, step by step, pilot type can be selected.4, electrical selection: voltage specifications should be preferred AC220V, DC24 is more convenient.5, according to the length of continuous working time to choose: normally closed, normally open, or sustainable power1) When the solenoid valve needs to be opened for a long time, and the duration is longer than the closing time, the normally open type should be selected;2) If the opening time is short or the opening and closing time is not long, choose normally closed type;3) However, some working conditions for safety protection, such as furnace and kiln flame monitoring, can not be selected normally open, should be selected for long-term power type.6, according to environmental requirements to select auxiliary functions: explosion-proof, check, manual, waterproof fog, water shower, diving.
