TWCV Series | API 6D Thin
Wafer Check Valve
C&C Industries
The C&C TWCV Series Thin Wafer Check Valve is an API 6D monogrammed, compact non-return valve designed for efficient backflow prevention in pipeline and process systems. Its single plate, self-acting design provides reliable operation while minimizing space, weight, and installation complexity.
Featuring a short pattern unibody construction, the TWCV Series reduces potential leak paths and eliminates the need for traditional flange gaskets through integrated body seals. Compared to full-body swing check valves, it offers a significantly lighter and more compact solution without sacrificing performance.
Built with forged steel bodies and stainless steel clappers, the TWCV Series delivers durability, corrosion resistance, and long-term reliability in demanding service environments.
Typical Applications:
Oil & gas pipelines, midstream systems, processing facilities, and general industrial flow control where space and weight are critical considerations

PERFORMANCE ADVANTAGES
Why the C&C TWCV Series Performs Where It Counts
SPACE-SAVING DESIGN FOR PIPELINE SYSTEMS
The thin wafer profile significantly reduces face-to-face length compared to traditional swing check valves. This allows for easier installation in tight piping layouts and reduces overall system footprint.
LIGHTWEIGHT CONSTRUCTION REDUCES INSTALLATION COSTS
With a forged, compact body design, the TWCV Series weighs substantially less than full-body alternatives. This simplifies handling, reduces support requirements, and lowers installation time in the field.
REDUCED LEAK PATHS WITH UNIBODY DESIGN
The unibody construction eliminates body joints and minimizes potential leak paths. Combined with integrated O-ring sealing, this improves system integrity and reduces the risk of external leakage.
DURABLE MATERIALS FOR LONG SERVICE LIFE
Forged steel bodies and stainless steel clappers provide strength and corrosion resistance across a range of operating conditions, ensuring long-term performance in demanding environments.
