Flanged Swing Check Valve Flanged End

Overview

The 300 PSI Flanged Swing Check Valve is designed to prevent reverse flow in fire protection, water supply, and industrial piping systems.
With a swing-type disc and flanged end connections, this valve provides reliable one-way flow control, low pressure loss, and stable performance under high working pressure.

Engineered in accordance with recognized international standards, it is suitable for both horizontal and vertical installations where dependable backflow prevention is required.

Product Description

This swing check valve features a hinged disc design that automatically opens with forward flow and closes quickly when flow stops or reverses, effectively preventing backflow and protecting pumps, pipelines, and system components.

The flanged end configuration ensures secure and leak-tight connections, while the straight-through flow path minimizes pressure drop during normal operation.
With a robust body structure and corrosion-resistant epoxy coating, the valve is built for long service life in demanding fire protection and water distribution systems.
