Lever Float Steam Trap Imported National Standard FT43 Series offers the advantage of being unaffected by pressure, temperature, or fluctuations in condensate flow. It ensures continuous drainage, discharging condensate immediately upon formation, with a minimum subcooling of 0°C, enabling heating equipment to achieve optimal efficiency.

Boxi Valve Co., Ltd.'s lever float steam trap features a valve seat always submerged below the liquid level, forming a water seal that prevents steam leakage. Its minimum working pressure is 0.01 MPa, with a maximum backpressure rate ≤85%. Equipped with an internal venting device and an automatic air vent valve, it effectively discharges non-condensable gases with high sensitivity, ensuring superior performance and long service life. Designed with a balanced double-seat structure, it achieves high drainage capacity in a compact size, making it particularly suitable for large heating equipment and heat exchange stations. It is the steam trap of choice for major heating systems.

Lever Float Steam Trap Imported National Standard FT43 Series

Structural Features

Utilizes a new valve mechanism (new SCCV closing method), offering excellent sealing and durability.

The balanced double-seat design allows for a smaller size and larger drainage capacity compared to conventional steam traps, demonstrating superior performance in high-capacity applications.

Includes a built-in bimetallic automatic air vent valve to prevent air binding and steam locking.

All components are mounted on the valve cover, allowing for maintenance without disassembling the valve from the pipeline, making it simple and convenient.
