Pressure relief valve (up to 75 m3, -30/0°C) ZD-2220L – how to choose the right one

ZD-2220L is a telescopic pressure relief valve for rooms with a volume of up to 75 m³, in the version for sub-zero temperatures down to -30°C, with wall or ceiling mounting. It differs from ZD-2220 by the letter L in its designation.

For a replacement, the surest route is to order under the exact designation given in the chamber's documentation.

If the cold room is new and the valve is selected from scratch, discuss the choice between versions with an AiFO advisor. When replacing, with the opening already cut, the exact code matters.

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

Ask a question
Are the ZD-2220L and ZD-2220 interchangeable?

Both items cover the same volume and the same temperature range, but for a replacement in an existing hole it is worth confirming the dimensions with an AiFO adviser before ordering.

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.
