Solenoid valve used in outside.When lightning strikes, thunderstorm coming, it will have a bad damage on irrigation systems. Years ago, electro-mechanical controllers and hydraulic systems were somewhat immune to lightning or electrical surges. With the advent of solid-state control products and electrically actuated solenoids, however, the need for improved surge protection began to increase. Even then, it was assumed that a certain amount of equipment replacement was the inevitable result of a severe lightning storm. But times have changed and so have customers' expectations.
We know customers have tired of the cost and manpower required to replace solenoids, as well as the landscape damage caused by lighting strikes. Troubleshooting lightning damage is our responsibility.
IMPROVEMENTS TO CONTROL PRODUCTS
Because of lightning damage to electronic components is very large, so we invented the electromagnet without diode. Surge protection features incorporated in themselves to proof lightning in some degree.
Also A ‘drop off’ design have a better control of the plunger. When we take down the solenoid on valves, the plunger and spring inside cannot be drop out.
PS, Stormiest Places in the World
Portions of Florida record the greatest number of thunderstorm days in the US with as many as 100-130 storm-days a year in an area inland of the Gulf Coast stretching from the Everglades north to the city of Lakeland (about 30 miles inland from Tampa) being the area of greatest activity.
The area that experiences the most thunderstorm days in the world is northern Lake Victoria in Uganda, Africa.
At one time Bogor, Indonesia (have a nick name: the ‘City of Rain’) has probably the highest annual rainfall in Java and is credited with a record 322 thunderstorms a year.
A phenomenal number of thunderstorms develop over northern Maracaibo Lake in Venezuela, resulting in the famous 'Catatumbo Lightning' phenomena (named after the river that flows into the lake and where the storms are most frequent).
Further inland the city of Bandung records an average of 218 thunderstorm days annually, the most for any site in Asia.
The Congo River Basin of Africa averages as many as 228 thunderstorms days as is the case in the city of Bunia, Republic of Congo.
In South America, the Amazon Basin reports up to 206 thunderstorm days at the town of Carauri.
Australia's stormiest location is Port George IV in Western Australia on the shores of the Timor Sea where 100 thunderstorm days a year are the norm.
