Miyawaki ES5 Inverted Bucket Steam Traps
Manufacturer: MIYAWAKI Inc.
Model: ES5
Features
No condensate logging on primary side
Intermittent or continuous discharge depending on condensate loads means no condensate stacking up on the primary side.
Superb durability
Offers superb durability thanks to the SCCV System valve and robust super lever, as well as stainless steel internal components.
Easy maintenance
For quick and easy maintenance, this model can be repaired directly in line.
Condensate recovery
With its high degree of back pressure tolerance, this model supports condensate recovery at pressures up to 90% of the upstream pressure.
Complete steam containment
A double steam separation mechanism (implemented with a U-shaped duct and inverted bucket) provides reliable steam separation and ensures trap tightness.
Free from steam and air locking
This model is free from steam and air locking due to a small air vent hole in the top of the bucket (discharges hot air and non-condensable gases).
*’SCCV System’ is an abbreviation of Self Closing and Centering Valve System.
Typical applications
ES5: Extremely small and lightweight, suitable for air conditioning equipment and devices, cleaning devices, dyeing devices, and similar applications.

- Maximum allowable pressure (PMA): 1,6 MPa (230psig) PMA is the pressure that can be tolerated by pressure-resistant parts (body).
- Maximum allowable temperature (TMA): 350℃ (662℉) TMA is the temperature that can be tolerated by pressure-resistant parts (body).
- Minimum operating differential pressure (⊿PMN): 0,01MPa (1.5psig) ⊿PMN is the minimum operating differential pressure between the trap inlet and outlet.

Installation Examples
To keep the drawing simple, bypass lines, valves, and other required equipment are not displayed.
If you wish to recover condensate, attach a check valve (CV model) and shut off valve on the trap’s outlet side.
