Miyawaki – Technical profile of a steam trap, pressure reducing valve and condensate handling equipment manufacturer

MIYAWAKI Inc. is a Japanese manufacturer of steam engineering equipment, including steam traps, pressure reducing valves, air vents, air traps, pumping traps, separators, strainers, check valves, vacuum breakers and steam trap management systems.

The company’s technical focus is the stable operation of steam and condensate networks. Its equipment is used to remove condensate, control steam pressure, recover heat and protect steam consumers from water hammer and wet steam.

Main product categories include:

• inverted bucket steam traps,
• ball float steam traps,
• thermostatic steam traps,
• thermodynamic disc steam traps,
• temperature control steam traps,
• direct acting pressure reducing valves,
• pilot operated pressure reducing valves,
• pumping traps,
• air vents and air traps,
• separators, strainers and vacuum breakers.

Steam trap selection must be based on application duty, not only connection size. The engineer must define condensate load, start-up load, differential pressure, back pressure, operating pressure, steam locking risk and air venting requirements.

Pressure reducing valves are used to reduce and stabilise downstream steam pressure before process users, heat exchangers, coils or utility stations. Selection requires inlet pressure, outlet pressure, steam flow, minimum and maximum load, steam quality, noise, downstream safety valve and bypass arrangement.

Pumping traps are used when condensate cannot return by gravity or available differential pressure. They are particularly relevant in heat exchangers operating under stall conditions, vacuum systems or high back pressure condensate return lines.

Miyawaki equipment is suitable for boilerhouses, heat exchangers, steam tracing, sterilisation, food processing, textile, chemical and HVAC steam systems. Correct integration of steam traps, pressure reducing valves, separators and condensate recovery equipment is essential for stable steam system operation.
