The balun box can be equipped with a pressure valve at extra cost.
The function of the pressure valve - if the instrument box is exposed to temperature changes - e.g. the difference between day and night temperatures or if heat is generated in the box during operation and the box cools down after operation - pressure changes and water vapour condensation occur in the sealed box.
In some cases, a vacuum may even be created, which can cause dust and moisture to enter.
Installing a valve with a pressure balancing function is a very simple way to provide ventilation and at the same time prevent vapour condensation and dust from entering the enclosure.
If you are interested in installing a pressure equalizing valve, add the valve offered above in the related products to your cart. The extra charge is the price of the valve.
