Thermostatic & Inverted Steam Traps

Explore an assortment of steam traps at F.W. Webb. Our collection features inverted and thermostatic steam traps and floats. Use a thermostatic trap with a temperature-sensing component to control the condensate discharge schedule; an inverted trap is a top-quality mechanical option that depends on gravity for operation. Made in durable cast iron, stainless steel, or brass, these traps can withstand the normal daily operation of an existing system. Use our convenient filters to narrow steam traps by end connection, working pressure range, size, and other variables. Browse quality steam traps from trusted makers such as Armstrong to find the best fit for your application.

Frequently Asked Questions

What are the 3 types of steam traps?

The three types of steam traps are thermostatic, thermodynamic, and mechanical:

  • Thermostatic: Operates based on the difference in temperature between subcooled and near-steam condensate.
  • Thermodynamic: Functions with the difference in kinetic energy between slow-paced condensate and high-velocity steam.
  • Mechanical: Uses the density difference between condensate and steam to perform properly.

What is the purpose of a steam trap?

The purpose of a trap is to discharge incondensable gasses, air, and condensate out of a steam system so that the live steam doesn't escape. This allows the system to operate efficiently.

Where are steam traps required?

Steam traps are required in the following locations:

  • Every 100 to 160 feet along a steam pipe
  • In front of manual valves that stay closed for a long period
  • Before pressure-reducing and control valves
  • Bottom of drops or risers
