High-Performance Design for Reliable Steam Systems

The Miyawaki Series G GC1N Ball Float Steam Trap operates based on the difference in density between steam and condensate. Its airtight, ball-shaped float utilizes buoyancy to automatically open and close the valve according to condensate levels — ensuring consistent discharge and preventing steam leakage.

Miyawaki’s advanced lever-float mechanism ensures smooth performance under demanding conditions. Additionally, some configurations use a double ported balance valve system, enabling a high discharge capacity within a compact body. This design minimizes operational force requirements while maintaining optimal condensate removal efficiency.
