Frequently Asked Questions

What is a non return valve?

A non return valve ensures that pneumatic pressure flows in a single direction and fitted to prevent reversed flow, also known as backflow.

What is the difference between a check valve and a non return valve?

Typically speaking they are the same and are often referred to by both names. To be specific, a non return valve allows the flow of pressure in one direction where a check valve is modernised, providing the same function and automatically prevents backflow.

Our non return valves are check valves due to their Acrylonitrile Butadiene Rubber seals that prevent backflow.

Where do you place a non return valve?

Our Aventics non return valves can be placed almost anywhere including in tight spaces and at any angle

How do you identify a non return valve?
