Introduction
In industrial steam systems, efficient condensate removal is critical for maintaining process efficiency, reducing energy losses, and ensuring reliable operation. The Miyawaki G11N Ball Float Steam Trap is engineered to provide continuous condensate discharge while maintaining excellent sealing performance and long-term durability.
Manufactured by Miyawaki, a recognized Japanese specialist in steam control technology, the G11N is designed to support a wide range of industrial applications where dependable condensate management is essential.

Why Choose the Miyawaki G11N Ball Float Steam Trap?
The Miyawaki G11N utilizes a continuous discharge float mechanism that removes condensate immediately as it forms. This helps maintain heat transfer efficiency while preventing condensate accumulation within the steam system.
Key benefits include:
Continuous condensate discharge at saturation temperature
Excellent sealing performance through SCCV technology
Resistance to steam and air locking
Easy inline maintenance
Support for condensate recovery systems
Durable cast iron construction
Reliable operation in demanding industrial environments
Miyawaki G11N Steam Trap Features
Continuous Condensate Discharge
The floating mechanism continuously discharges condensate without allowing it to accumulate in the primary side of the system. This helps maintain stable operating conditions and efficient heat transfer.
SCCV Sealing Technology
Miyawaki's SCCV (Self Closing and Centering Valve) System enhances valve durability and sealing performance. The design minimizes wear and contributes to reliable long-term operation.
Prevention of Steam and Air Locking
An integrated air vent allows rapid startup and effective air removal. This helps maintain operational stability and reduces interruptions caused by trapped air.
Easy Maintenance
All valve components are attached to the cover assembly, simplifying inspection and maintenance procedures. The trap can be serviced directly in the pipeline, helping reduce downtime.
Condensate Recovery Capability
The G11N is designed to tolerate back pressure, making it suitable for condensate recovery systems where energy efficiency and resource conservation are priorities.
