All Stainless Steel
Product Overview
MIYAWAKI ES8N/ES8NF is an inverted bucket steam trap featuring the extended lifespan SCCV® design. By allowing the inverted bucket to float freely within the disc holder, it reduces impact force during condensate discharge and minimizes wear, effectively extending overall equipment service life. Ideal for condensate drainage in steam systems.
Core Structure & Design
Key components of the SCCV® design:
| Component | Function |
|---|---|
| Lever | Connects bucket to disc, transmits motion |
| Seat | Seals with disc, controls medium flow |
| Disc | Opens/closes with bucket motion, regulates flow |
| Inverted Bucket | Core floating component, senses condensate via buoyancy |
| Disc Holder | Provides bucket floating space, cushions impact |

Flow Characteristics
The flow vs operating pressure relationship for ES8N can be referenced in the flow chart. Condensate discharge flow (kg/h) increases linearly with pressure at different operating conditions, suitable for various steam system load requirements.
