Miyawaki
Miyawaki ESU5 Inverted Bucket Steam Traps
Manufacturer: MIYAWAKI Inc.
Model: ESU5
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
The SCCV System valve and robust super lever work together to provide superb durability, while the stainless steel internal components further enhance the overall strength and reliability.
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 effectively prevents steam and air locking because a small air vent hole at the top of the bucket continuously discharges hot air and non-condensable gases.
*’SCCV System’ is an abbreviation of Self Closing and Centering Valve System.
Typical applications
Body and cover made of stainless steel, and suitable for food equipment, medical equipment and other applications.
