WCB Cast Steel Swing check valve is an automatic valve widely used in pipeline systems, primarily designed to prevent medium backflow and ensure unidirectional flow in piping systems.
Working Principle
The cast steel swing check valve operates through a mechanism called the "swing disc".
Flow Direction: When fluid moves toward the pipeline outlet, the valve opens automatically.
Closing Mechanism: The swing disc rotates on durable bearings and closes against the valve seat when flow stops, effectively preventing backflow.
Unidirectional Flow: The disc ensures one-way fluid movement, maintaining system stability.
Key Features
Superior Sealing
Swing-in design provides high sealing performance, preventing liquid backflow.
Durability & Stability
The swing disc mechanism ensures long service life and reliable operation.
