Pressure relief valve (75-5000 m3, -30/0°C, wall mounting) ZD-2230 – how to choose the right one
The ZD-2230 is a pressure relief valve for chambers with a volume from 75 to 5000 m3, in the version with a heating element and wall mounting. The manufacturer states the operating pressure at around 100 Pa, and a temperature alarm sensor is included.
The ZD-22xx family covers four combinations: with and without heating, in the wall and in the ceiling. The ZD-2230 is the one to reach for in a freezer chamber when the wall is the only free surface left.
A temperature alarm sensor is a feature the valves described by power alone do not have. Its signal can be routed to a controller and treated as confirmation independent of the chamber sensor.
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
- Medium and large-volume freezer warehouses
- Chambers connected to a temperature monitoring system
- Fit-outs where the ceiling is taken up by the evaporator
- Facilities requiring an alarm signal from the valve
FAQ
Frequently asked questions

Ask a questionWhat is the heating element for in the valve?
In a freezer chamber, moisture settles on the passage and freezes. Heating keeps the channel clear, which is why versions without it are designed for the positive range.
Will one valve serve a 4000 m3 chamber?
The manufacturer's stated range of 75-5000 m3 covers volumes like that. For the largest facilities, though, it is worth comparing it with the ZD-2260, designed for above five thousand.
