Welcome to Nichiboku's industrial Blog
Introduction
The Miyawaki GC1N Ball Float Steam Trap exemplifies Japan’s engineering excellence in steam management technology. Designed to deliver continuous condensate discharge and ensure efficient heat transfer, this unit provides stable operation even under varying steam loads — making it ideal for critical industrial systems where precision and reliability are essential.

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.
