Pressure relief valve (40 W, 0/-30°C) ZD-12546 – how to choose the right one

The ZD-12546 is a pressure relief valve for freezer rooms, powered at 220-240 V, with a 40 W draw and intended for wall mounting. The operating range covers temperatures from 0 to -30°C.

The catalogue lists four valves with the same parameters and different numbers: ZD-12546, ZD-17963, ZD-20334 and ZD-20916. The description does not distinguish between them, so when ordering, only the full designation decides.

There is one practical conclusion: the number needs to be copied from the old valve's nameplate or from the cold room's documentation. Selecting by parameters alone will give four matching results and no clue as to which one will fit the existing opening.

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

  • Replacing a valve in a freezer room under the same item code
  • Installations with free wall space
  • Servicing carried out according to the number in the documentation
  • Cold rooms operating down to -30°C

Ask a question
What is the difference between the ZD-12546 and the ZD-17963?

The datasheets for both items give the same electrical data, the same mounting method and the same temperature range. The difference lies outside the catalogue description, which is why selection is based on the number rather than the parameters.

Can this valve be mounted in the ceiling?

The description specifies wall mounting only. Other items are intended for the ceiling, for example the ZD-21216 or the ceiling versions from the ZD-2231 and ZD-2251 families.
