Inverted Bucket Steam Trap 883/883F PN16 Cast Iron Threaded Mechanica

Description

Buy Steam Trap 883F Bucket Type PN16 Cast Steel Flanged Mechanical

The 883/883F inverted bucket steam trap from VALVEHU is a high-performance condensate discharge device engineered for demanding steam systems. Designed with robust construction and superior sealing characteristics, this mechanical steam trap operates on the inverted bucket principle, making it exceptionally resistant to backpressure. It is ideal for applications where condensate needs to be effectively drained while preventing steam loss.

This bucket-type trap is available in body materials including GGG40 ductile iron, A216 WCB carbon steel, and A351 CF8 stainless steel, offering excellent compatibility with a wide range of industrial environments. Internals such as the valve seat and strainer are made of corrosion-resistant A240 304 stainless steel, while the valve stem is made from A193 B7 alloy steel for added mechanical durability. The trap is equipped with a float mechanism that automatically opens and closes the discharge valve based on the presence of condensate.

The 883 series is suitable for steam systems in power plants, chemical processing, food and beverage, textile, and HVAC industries. It can handle differential pressures efficiently and ensures zero steam leakage, improving energy efficiency and system reliability. Uniform external dimensions (270x178x322mm) across DN20–DN50 models make installation and replacement simple and standardized.

If you’re looking for reliable condensate discharge without energy loss, this trap is an excellent solution.

Main Valve Component Materials

What industries are best suited for this steam trap?
It’s ideal for steam systems in petrochemical, textile, HVAC, food processing, and power generation.

Is the 883/883F suitable for high-pressure applications?
Yes, it is designed to handle differential pressures with high resistance to backpressure.

What materials are used for corrosion resistance?
Key components like the strainer, valve seat, and stem are made of A240 304, SS316, and A193 B7 for durability.

How does the inverted bucket mechanism work?
It uses a float (bucket) that rises or falls with condensate levels, automatically opening and closing the discharge valve.

Can the same dimensions be used for all DN sizes?
Yes, from DN20 to DN50, all sizes share uniform outer dimensions for easier replacement and piping design.
