Swing Check Valve

Swing Check Valve is an automatic non-return valve designed to prevent reverse flow in pipeline systems. It uses medium pressure and disc weight to control opening and closing, ensuring one-way fluid flow. With lower flow resistance than lift check valves, it is especially suitable for large-diameter pipeline applications.

Applications

Swing Check Valve is widely used in oil & gas pipelines, water treatment systems, power plants, chemical industries, petroleum facilities, and large-scale industrial piping systems. It is commonly selected by EPC contractors, engineering companies, valve distributors, and industrial maintenance suppliers for backflow prevention.

Core Features

1. Automatic Backflow Prevention

Uses medium pressure and disc self-weight to automatically prevent reverse flow and protect pipeline systems.

2. Low Flow Resistance Design

The disc rotates around a hinge shaft, providing lower pressure loss and better performance in large-bore pipelines.

3. Flexible Installation Options

Suitable for horizontal pipelines and can also be installed on vertical pipelines with upward flow or inclined pipelines.

4. Multiple International Standards Available

Available in API, DIN, GOST, JIS, GB, and other standards to meet global industrial requirements.
