CVA Series | API 6D Swing Check Valve
C&C Industries
The C&C CVA Series Swing Check Valve is a high-performance API 6D valve designed to prevent backflow in critical oil & gas and industrial pipeline systems. Engineered for reliability in high-pressure service, it delivers dependable shutoff and long-term durability across a wide range of operating conditions.
Available in pressure classes from 150 through 2500 and sizes from 2” through 24”, the CVA Series is built to meet demanding pipeline and process requirements. Constructed from carbon steel, low temperature carbon steel, or stainless steel, it provides flexibility for both standard and severe service environments.
With features like a stainless steel clapper, full bore design, and in-line serviceability, the CVA Series ensures efficient flow, reduced pressure drop, and simplified maintenance in critical systems.
Typical Applications:
Pipelines, oil & gas production, transmission systems, compression, refining, petrochemical processing, and high-pressure industrial flow systems

PERFORMANCE ADVANTAGES
Why the CVA Series Performs Where It Counts
RELIABLE BACKFLOW PREVENTION
IN CRITICAL SYSTEMS
The swing check design allows flow in one direction while automatically preventing reverse flow. In real-world operation, this protects compressors, pumps, and upstream equipment from damage caused by backflow events.
FULL BORE DESIGN FOR MAXIMUM
FLOW EFFICIENCY
A full opening design minimizes pressure drop across the valve, improving system efficiency and maintaining flow capacity in high-demand pipeline applications.
ENGINEERED FOR HIGH-PRESSURE &
PIPELINE SERVICE
With pressure ratings up to Class 2500 and API 6D compliance, the CVA Series is built for pipeline and severe service environments where failure is not acceptable.
ROBUST MATERIAL OPTIONS FOR
SEVERE ENVIRONMENTS
Available in WCB, LCC, and CF8M materials, the CVA Series can be matched to temperature, pressure, and corrosion requirements, ensuring long-term durability in demanding service conditions.
