Product Description

How does a non-return valve work?

A non-return valve usually has only two openings in the body, with a closing member between them. When fluid enters the valve, its pressure opens the closing mechanism. If the fluid attempts to flow back through the valve in the wrong direction, the closing member is forced back over the entrance of the valve, preventing any flow.

Our Non-return valves work automatically, which means that most are not controlled by a person or an external control but by the media flow itself. Depending on precisely what a non-return valve is used for, where it is used, the media flow, and the budget available, various designs are available according to the specific application. Types of non-return valves include those designed using a diaphragm, a swing or tilting disc, a stop, a lift, or a ball non-return valve.
