Flanged Cast Iron Swing Check Valve Customized For Liquefied Gas

Flanged Check Valves Introduction

The swing check valve is also called a one-way valve or a non-return valve. Its function is to prevent the backflow of the medium in the pipeline. The opening and closing parts are opened or closed automatically by the flow and force of the medium to prevent the backflow of the medium. The check valve belongs to the automatic valve category. It is mainly used in pipelines where the medium flows in one direction. The medium is only allowed to flow in one direction to prevent accidents. This type of valve should generally be installed horizontally in the pipeline.

Check Valve Materials of main parts

Structural features of the check valve
