Pressure relief valve (up to 75 m3, -30/0°C) ZD-2220 – how to choose the right one
The ZD-2220 is a telescopic pressure relief valve for rooms with a volume up to 75 m3, in the negative version down to -30°C, mounted in the wall or the ceiling. The catalogue also carries the ZD-2220L item alongside it, described the same way.
A letter at the end of a code usually marks a construction variant, but the manufacturer does not explain its meaning here. For a replacement, it is safer to stick to the designation taken off the old unit.
This item and the ZD-2222 form a temperature pair in the smaller size within the family. The construction stays shared; only the regime they are meant to work in differs.
How to match the fittings to the panel thickness and the weight of the door – we explained it in the selection guide for this category.
Where it works
- Back-of-house freezers with a volume up to several dozen cubic metres
- Chambers with a limited choice of passage location
- Fit-outs with a non-standard panel thickness

Ask a questionDoes the ZD-2220 need an electrical supply?
This item's datasheet gives no electrical data, though heating does appear in the freezer versions in this range. It is worth confirming this before preparing the installation.
Which variant should I order if I don't know the letter at the end of the code?
A photo of the rating plate and the hole's dimension help here. Without that, both items look the same in the catalogue.
