2W series two-position two-way direct-acting solenoid valve

2W series two-position two-way direct-acting solenoid valve

1, two-position two-way right-angle solenoid valve pipeline parameters selection method

1) Determine the diameter (DN) according to the size of the diameter of the pipe or flow rate requirements at the site.

2) connection method, usually flange connection for greater than DN50, less than DN50 can be selected arbitrarily according to customer requirements.

2, according to fluid parameters to choose smc solenoid valve: material, temperature group

1) corrosive liquids: choose corrosion-resistant normally open solenoid valve and all stainless steel: can be used for food super clean liquid: can choose stainless steel material food grade.

2)high temperature liquid: choose heat-resistant insulating materials, sealing materials made of solenoid valve and piston type.

3)Liquid condition: large to gas, liquid, or mixed, especially when the diameter exceeds DN25, must be distinguished.

4) liquid viscosity: generally not less than 50 cSt, if beyond this range, a high viscosity solenoid valve should be selected.

3, according to the pressure parameters to choose the solenoid valve: principle and structure varieties

1) rated pressure: this parameter is the same as other commonly used valves, determined by the rated pressure of the pipeline.

2)The working pressure of the normally open solenoid valve for liquid: When the working pressure is small, the principle of direct-acting or segmented direct-acting should be used:* When the working differential pressure is greater than 0.04 Mpa, direct-driven. Staged direct-acting and pilot type two.

4、Electrical selection: AC220V.DC24 is recommended.

5, according to their own working time to choose.

1) In the case of solenoid valve open for a longer period of time, and its duration is greater than the closure, the normally open type should be selected.

2) if the open time is shorter, or open and close time is less, choose normally closed mode.

3) but some in ** protection conditions, such as furnace flame monitoring, can not choose normally open mode, should be selected for a long time energized.

6. Choose explosion-proof, check, manual, waterproof fog shower, submersible according to the needs of the site.
