Non Return Valve Introduction

Product Description

FlowBiz non-return valve, also known as a check valve. Our Valve is organized to allow fluid to flow in one direction only, preventing the liquid or gas from flowing upstream of the Valve. In this guide, we look at how a non-return valve operates and what a non-return valve is used for, including some of the applications in which you might find one.

Our non-return Valve is a single-way valve that allows the fluid to flow only in one direction. The main volume of non-return valves is their working of allowing flow in the downstream direction and preventing the flow in the upstream direction.

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 the 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.

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 exactly what a non-return valve is used for, where it is used, the media flow, and the budget available, there are various types of designs to select from 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.
