Deskripsi
WCB Flanged Free Float Steam Trap
Model : CS41H-100C DN20
Brand : Shanghai Valve Factory
Product Overview
The CS41H-100C is a flanged free float steam trap designed for continuous discharge of condensate in high-pressure steam systems. Its free-floating ball mechanism ensures stable operation, automatic air venting, and minimal steam loss. The WCB body makes it suitable for demanding industrial environments, including power generation, petrochemical, and textile applications.

Application Areas
Ideal for:
- High-pressure steam heating systems
- Condensate recovery networks
- Petrochemical and refinery units
- Textile and dyeing machinery
- Pharmaceutical and food processing
- Power station auxiliary steam lines
The free float design ensures continuous drainage without water hammer, and the automatic air venting prevents startup delays and air locking.
