812 Cast Iron Inverted Bucket Steam Trap

The Armstrong 812 Cast Iron Inverted Bucket Steam Trap is engineered for reliable performance in industrial steam and HVAC systems. Built with a ASTM A48 Class 30 Cast Iron body, this inverted bucket steam trap delivers efficient operation and long service life.

800 Series Inverted Bucket Steam Trap in cast iron for horizontal installation, with continuous air venting at steam temperature, free-floating stainless steel mechanism, and discharge orifice at the top of the trap.

The most reliable steam trap known—the inverted bucket—provides efficient condensate drainage of virtually all types of steam-using equipment. Put the inverted bucket to work in a tough cast iron package, and you have the best of both worlds. Because they operate efficiently for longer periods of time, Armstrong cast iron inverted buckets add solid energy savings to lower replacement/labor costs. All Armstrong cast iron inverted bucket steam traps are repairable for even bigger maintenance savings.
