In brief
Prices and stock levels are in the B2B shop. Sets of cold room fittings are put together to order.
The ZD-20334 is a pressure relief valve drawing 40 W, powered at 220-240 V and fitted into the wall of a chamber working in the 0 to -30°C range. The catalogue describes it the same way as the other three valves in this group.
This situation comes up when a single distributor carries versions from several manufacturers with similar specifications. For the user, this means one thing: a replacement is chosen by code, not by the data table.
If the chamber is still under warranty or covered by a service contract, changing the code can be further restricted by the terms of that agreement. It is worth checking this before deciding on a cheaper equivalent.
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
FAQ
Have not found your answer? Give the panel thickness and the door dimensions – we will select a complete set of fittings.
Ask a questionThe catalogue data for both items match, but the mounting hole dimensions are not given. Without confirming them, swapping one for the other remains a risk on the installation side.
Then a photo of the unit from the chamber side, together with the measured hole diameter, helps. On that basis we will narrow the choice down to one item.
