FAQs (Frequently asked questions)

Find detailed answers to common questions about Swing Check valve in our Knowledge centre. 

What is a swing check valve?

A swing check valve is a non return valve that uses a hinged disc that opens to allow forward flow and closes automatically to prevent reverse flow.

What is the main advantage of a swing check valve over other types?

Swing check valves offer lower resistance to forward flow compared to lift check valves and are ideal for horizontal line installations with steady flow. They are also generally easier to maintain due to their accessible internal design.
