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 operating pressure is around 100 Pa, and a temperature alarm sensor is included.
Valves for 75–5000 m³ come in four combinations: heated and unheated, wall- and ceiling-mounted (ZD-2230, ZD-2231, ZD-2250, ZD-2251). ZD-2230 is the one to choose for a freezer room when the wall is the only free surface.
All valves in this volume group have a temperature alarm sensor. How it is connected to the controller or monitoring system should be decided at the design stage.
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 room, moisture settles in the passage and freezes. Heating keeps the channel clear, which is why a heated version is chosen for sub-zero temperatures.
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.
