Pressure relief valve (up to 75 m3, -30/0°C) ZD-2220L – how to choose the right one
The ZD-2220L is a telescopic pressure relief valve for rooms with a volume up to 75 m3, in the negative version down to -30°C, with wall or ceiling mounting. In the catalogue, only the letter in the code sets it apart from the ZD-2220 item.
Suffixes like this are sometimes a trace of a generation change or a different length version. Since the datasheet does not explain them, the only sure route is to order under the exact designation given in the chamber's documentation.
If the chamber is new and the valve is being chosen from scratch, the difference has no practical bearing. The problem only comes up on a replacement, once the hole has already been cut.
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
- A replacement under the designation taken off the unit
- Freezer chambers with a volume up to seventy-five cubic metres
- Installations following the chamber manufacturer's parts list
- Fit-outs with the passage routed through the ceiling

Ask a questionAre the ZD-2220L and ZD-2220 interchangeable?
The catalogue description shows no difference, but does not rule one out either. For a replacement in an existing hole, it is worth confirming the dimensions with the manufacturer.
Where do I get the correct designation from?
The most reliable source is the plate on the valve or the chamber's as-built documentation. An old invoice record is usually enough too.
