DESCRIPTION

Design Features of API 6D Tilting Disc Check Valve

The GMK API 6D Tilting Disc Check Valve adopts a single-piece tilting disc structure with internal hinge pins positioned above the valve centerline. This design enables fast response to flow changes and improves sealing reliability.

The streamlined body and disc design reduce flow resistance and pressure loss, providing efficient fluid performance. The valve can be installed in horizontal pipelines and vertical pipelines with upward flow direction.

For large diameter applications, the compact wafer-style design allows installation between flange faces, reducing weight and saving installation space.

Advantages of Industrial Tilting Disc Check Valve

Prevents reverse flow and protects pipeline systems.
Low flow resistance improves system efficiency.
Fast disc closing reduces water hammer risks.
High-performance spring design provides reliable operation.
Excellent corrosion resistance and mechanical strength.
Compact structure saves installation space.
Suitable for high-flow and high-pressure applications.
Provides stable sealing performance under changing flow conditions.

Working Principle of Tilting Disc Check Valve

The valve operates automatically according to pipeline flow conditions. When fluid pressure reaches a sufficient level, the disc tilts open to allow forward flow. When the flow stops or reverses, the disc quickly returns to the seat to prevent backflow.

The unique disc rotation design reduces closing time and minimizes pressure surges caused by sudden flow changes.
