Description
Stainless Steel Swing Check Valve Threaded Full Port
Stainless Steel Threaded Full Port Swing Check Valves are designed to help prevent reverse flow in compatible piping systems while maintaining a full-flow passage through the valve body. The swing-check design opens automatically with forward flow and closes when flow reverses, helping protect downstream equipment and piping.
This valve is identified as designed to ASME B16.34, tested to API 598, and rated for 200 PSI working pressure at 350°F. Country of origin is Taiwan.

Swing Check Valve Operation
A swing check valve uses an internal hinged disc that opens when fluid moves in the intended flow direction. When forward flow slows or reverses, the disc swings back toward the seat to help stop reverse flow.
This automatic operation does not require a manual handle or actuator, making the valve useful for systems where backflow prevention is needed without operator input.
The full-port configuration helps maintain a larger internal flow area through the valve than reduced-port designs.

Swing Check vs. Ball Valve
Swing Check Valve
- Operates automatically with flow
- Designed to prevent reverse flow
- No manual handle required
- Uses an internal swinging disc
- Primarily used as a non-return valve
Ball Valve
- Manually or automatically actuated
- Designed primarily for shutoff and isolation
- Uses a rotating ball
- Does not automatically function as a check valve
- Different purpose from a swing check valve
Common Applications
Commercial & Mechanical Piping
- Water piping systems
- Equipment discharge lines
- Pump discharge piping
- Utility piping
- General backflow-prevention service
Industrial Service
- Process piping systems
- Equipment protection
- Flow-control assemblies
- Compatible liquid-service applications
- Applications requiring stainless steel construction
Installation & Selection Guidance
- Confirm the required nominal valve size before ordering.
- Verify threaded connection compatibility with the mating piping.
- Install the valve in the correct flow direction.
- Confirm that the swing-disc orientation is appropriate for the installation position.
- Verify that the 200 PSI at 350°F rating is suitable for the intended service.
- Confirm media compatibility with the stainless steel valve construction and internal components.
- Use an appropriate thread sealant for the system media, pressure, and temperature.
- Apply thread sealant according to the sealant manufacturer's instructions.
- Use appropriate wrenching surfaces during installation.
- Avoid excessive installation torque that could damage the valve body or piping.
- Confirm pressure and temperature requirements before installation.
- Installation should comply with applicable piping codes and project specifications.
