ASTM A216 WCB Free Float Steam Trap, ISO 6552, DN25, PN16

Key Specifications / Features

The Free Float Steam Trap features a carbon steel ASTM A216 WCB body, providing excellent strength and durability. Designed to ISO 6552 and EN 26704 standards, it has a 1-inch (DN25) size, Class 150 LB (PN16) pressure rating, and CS11H threaded ends for secure installation. This steam trap efficiently removes condensate from steam systems, ensuring optimal performance in industrial and energy applications.

The Free Float Steam Trap is one of the most advanced steam traps available, with product quality and manufacturing processes that meet international standards. The trap's high float design ensures effective sealing performance, with the entire sphere serving as the sealing surface, contributing to a long service life. A key advantage of the Free Float Steam Trap is its built-in drain valve, which is highly sensitive and helps extend the trap's overall lifespan. These traps excel under varying pressure, temperature, and condensate flow fluctuations, providing continuous drainage. With minimal undercooling (as low as 0°C), they help achieve optimal efficiency for heating equipment. The trap operates with a minimum working pressure of 0.01 MPa and can handle up to 85% back pressure.
