Product Description

Introduction

Working Principle
Under the action of the fluid pressure flowing in one direction, the valve disc opens; when the fluid flows in the opposite direction, the fluid pressure and the self - weight of the valve disc act on the valve seat, thereby cutting off the flow.
Installation Precautions
The check valve should not bear weight in the pipeline. Large - scale check valves should be independently supported to avoid being affected by the pressure generated by the pipe system.
During installation, pay attention that the direction of medium flow should be consistent with the arrow direction on the valve body.
Swing check valves can be installed on horizontal, vertical, or inclined pipelines, and the installation position is not limited.
