Pressure relief valve (40 W, 0/-30°C) ZD-20916 – how to choose the right one

The ZD-20916 is a wall-mounted pressure relief valve for freezer chambers, drawing 40 W and powered at 220-240 V, working in the 0 to -30°C range. It belongs to a group of four valves with the same specification.

For a group like this, a sensible stock strategy is to keep one chosen code and consistently replace the whole fleet of chambers with it. After a few service visits, the stock stops being a set of four near-identical items.

Until that happens, every replacement needs the hole in the panel checked. The valve passes through the full thickness of the wall, so a mismatch only shows up after cutting.

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

  • Standardising the valve fleet across several chambers
  • Replacements planned as part of periodic servicing
  • Freezer chambers powered from a 230 V board
  • Fit-outs where the ceiling stays out of reach

Ask a question
Does the valve have to pass through the full thickness of the panel?

That is how this type of unit works: a channel connects the inside of the chamber with the surroundings. The panel thickness needs to be measured before ordering.

How often should the valve's passage be checked for clearance?

In practice it is checked at every chamber service, since a fault often only shows up as resistance when opening the door.
