Pressure relief valve (500-700 m3, -30/0°C) ZD-1403 – how to choose the right one
The ZD-1403 is a pressure relief valve in the freezer version, intended for chambers with a volume from 500 to 700 m3, drawing 36 W, with a body made entirely of nylon. The construction is not telescopic.
The rotary diaphragms this family works on are moved by the pressure difference itself, whether positive or negative. The action is gradual, with no sudden opening, which limits a rush of warm air into the interior.
No telescope means a fixed passage length. With thicker panels, or a wall with additional fit-out, this limit needs to be checked at the design stage, not at fitting.
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
- Large freezer warehouses measured in hundreds of cubic metres
- Chambers with a known, unchanging partition thickness
- Installations where a gentle pressure equalisation matters
- Fit-outs requiring a body resistant to moisture
FAQ

Ask a questionWhat does the nylon construction give?
The manufacturer states this material as uniform across the whole body. Nylon does not corrode and withstands moisture, which matters in real terms for a part passing through a partition.
How does the ZD-1403 differ from the ZD-1404?
In the temperature range: this valve is the freezer version, the other works in the positive range. Power draw and construction stay the same in both.
