Check valves: Control the air flow in your ventilation system

Discover our range of check valves, essential components for the efficient management of your ventilation system, available in robust PVC or durable aluminum. Designed for easy connection to your ventilation ducts or air extractors, our check valves are available in diameters ranging from 100 mm to 315 mm, adapting to a variety of configurations.

Non-return valves are particularly essential when setting up a CO2-enriched cultivation area, as they prevent CO2 from escaping when the extraction system is switched off. They are also very useful for isolating a grow room from its external climatic environment, helping to maintain stable, optimal conditions for your plants. To complement our check valves, you'll also find our selection of ventilation grilles to complete your ventilation system.

FAQ Check valves

What is the purpose of a check valve in a ventilation system?

A check valve ensures that the air flow circulates in one direction only, preventing air from flowing backwards when the extractor is switched off. This is essential to maintain ventilation efficiency and containment of specific atmospheres such as CO2-enriched spaces.

How do I choose the right check valve size for my installation?

The check valve size must match the diameter of your ventilation ducts and air extractors. We offer diameters ranging from 100 mm to 315 mm to suit most configurations.

What's the difference between PVC and aluminum check valves?

PVC check valves are generally lighter and more economical, while aluminum ones offer greater heat resistance and durability. The choice will depend on your specific needs and the environment of your installation.
