Fushiman BLF10 type super large volume trap for steam

Manufacturer: Fushiman Co.,LTD.
Model: BLF10

Model	Nominal Diameter	Method	Maximum Operating Pressure	Maximum Operating Temperature	Body Material	Connection
BLF10	40–65	Float	1.0 MPa	220°C	FC	Flanges

Features

The main mechanism is mounted on the float chamber flange with a simple and robust structure, making it resistant to damage and less prone to failure.
The valve body uses a seat-type structure with a special high-pressure-resistant float, allowing use across a wide range from low to high pressure.
Equipped with an external automatic air vent valve.

As the water level of the drain entering from the upper inlet rises, the float gains buoyancy and begins to rise. When it reaches the specified water level, the float lifts and opens the valve. The drain inside the float chamber is then discharged to the outlet side by the inlet pressure.
When the drain discharge ends and the water level in the float chamber drops, the float also lowers due to its own weight, closing the valve to prevent steam from discharging. This cycle repeats continuously.
