The classification standard of electromagnetic valve protection grade has extremely strict division. Since the 1980s, the international standard for classification of electromagnetic valve protection grade has been introduced in China. The protection grade system software IP (International & Protection) is drafted and formulated by IEC (International Electrotechnical Commission International Electric Welder Federation).

Special water supply solenoid valve the system software classifies machines and equipment according to their anti fouling and anti moisture characteristics. The IP protection grade of high-quality water supply solenoid valve is composed of two data. The first number represents the level of dust separation and foreign object prevention of machine equipment and household appliances, and the second number represents the closed level of machine equipment and household appliances against internal moisture and moisture intrusion. The larger the data, the higher the protection level.

Safety protection type solenoid valve

First data of solenoid valve:

0-custom feed water solenoid valve shows no safety protection and no unique safety protection for external people or objects.

1 - to avoid the invasion of solid objects > 50 mm, to prevent the body (Palm) from touching the internal parts of household appliances due to accidents, and to avoid the invasion of external factors > 50 mm.

2 - to avoid the invasion of solid objects > 12mm, to avoid the body (fingers) touching the internal parts of household appliances due to accidents; to avoid the invasion of external factors > 12mm.

3 - to avoid the invasion of solid objects > 2.5mm, and to avoid touching the internal parts of household appliances by the tiny external factors of > 2.5mm.

4 - to avoid the invasion of solid objects > 1.0 mm, and to avoid touching the internal parts of household appliances by minor external factors > 1.0 mm.

5 - it shows that it is antifouling and can completely avoid the invasion of foreign objects, and the amount of dust that invades is not easy to endanger the normal operation of household appliances.

6-indicates antifouling, completely avoiding foreign objects and dust invasion.

Stainless steel plate solenoid valve

Specification second data:

0 - indicates no safety protection.

1 - to avoid the invasion of water seepage, vertical dripping water droplets are not easy to cause harm to household appliances.

2-indicates that water seepage can still be avoided when the deviation is 15, and it is not easy to cause harm to household appliances when the machine equipment and household appliances are skewed for 15.

3 - it means to avoid water intrusion, waterproof and rain proof, or to avoid the damage caused by the water sprayed from the vertical direction < 60 into the machine equipment and household appliances.
