Description
Stainless Steel Swing Check Wye Pattern Threaded
Stainless Steel Wye Pattern Threaded Swing Check Valves are designed to help prevent reverse flow in compatible piping systems while using a wye-pattern body configuration to support smoother directional flow through the valve. The swing-check mechanism opens automatically with forward flow and closes when flow reverses, providing automatic backflow protection without manual operation.
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.

Wye Pattern Swing Check Operation
A wye pattern swing check valve uses an internal hinged disc that opens in response to forward flow and closes when flow reverses. This automatic action helps prevent backflow through the piping system.
The wye-pattern body provides an angled internal flow path compared with a more traditional straight-body swing check configuration.
No manual handle or actuator is required because the valve operates in response to system flow direction.
Why Choose a Wye Pattern Swing Check Valve?
Automatic Backflow Prevention
- Opens automatically with forward flow
- Closes when flow reverses
- Helps protect pumps and downstream equipment
- No manual operation required
- Suitable for continuous piping-system protection
Wye Pattern Body
- Angled body configuration
- Supports directional flow through the valve
- Provides access to the internal check mechanism
- Useful in compatible industrial and mechanical piping systems
- Distinct body geometry from a standard straight-pattern check valve

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 wye-pattern body orientation is appropriate for the installation.
- 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.
