The box can be supplemented with a pressure valve at an additional cost.
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 condensation of water vapour occur in the sealed box.
In some cases, a vacuum may even be created, which can cause dust and moisture to enter.
Installing a pressure equalizing valve is a very simple way to provide ventilation while preventing vapor condensation and dust from entering the enclosure.
If you are interested in installing a pressure valve, add the valve offered in the Accessories category to your cart. The extra charge is the price of the valve.
