What are the differences in protection levels of two-position two-way solenoid valves

Solenoid valve protection level is very different, although there is a clearer grade difference, but many people are not enough understanding of this aspect, which will lead to purchase errors, even though the relevant specification standards have been introduced a long time ago, but still many users do not know enough, for this issue to explain in detail.

Gas two-position two-way solenoid valve This system is graded from several levels according to its anti-fouling, anti-internal moisture and other characteristics. High-quality water supply solenoid valve IP protection grade is composed of two data sets, a set of values on behalf of mechanical equipment and appliances dust and moisture resistance, two sets of values on behalf of mechanical equipment and appliances moisture resistance, the larger the value, the higher the level of protection.

Protective solenoid (valve)

The first parameter is the two-position two-way solenoid valve model.

0-custom water supply solenoid valve indicates that there is no special safety protection against outside persons or objects.

1-Indicates protection from solid objects exceeding 50 mm, protection from human (palm) contact with internal parts of the appliance, and protection from external elements exceeding 50 mm.

2-Indicates protection against solid objects exceeding 12 mm, preventing the human body (fingers) from accidentally touching the internal parts of the appliance; protection against external factors exceeding 12 mm.

3-Indicates to prevent the intrusion of solid objects exceeding 2.5 mm and to prevent tiny external factors exceeding 2.5 mm from touching the internal parts of the appliance.

4-Indicates prevention of intrusion of solid objects exceeding 1.0 Mm, and prevention of piston type normally open solenoid valve from touching internal parts of the appliance when minor external factors exceed 1.0 Mm.

5-Indicates anti-pollution, completely preventing the intrusion of foreign substances and the amount of dust intrusion is not likely to affect the normal operation of the appliance.

6-Indicates anti-pollution, completely prevents the solenoid high-pressure valve from being invaded by foreign substances, and completely prevents the intrusion of dust.

Parameter 2.

0-Indicates that there is no safety protection.

1-Indicates to prevent infiltration, corrosion-resistant normally open solenoid valve vertical dripping water droplets are not easy to cause harm to the appliance.

2- indicates that tilt 15 can still prevent infiltration, mechanical equipment and appliances tilt 15 water leakage is not easy to cause harm to the appliance.

3 - said to prevent rain spray, prevent rainwater infiltration, or prevent water in the vertical direction of less than 60 degrees into the machinery and appliances caused by damage.
