Spirax Sarco FT44 Carbon Steel Ball Float Steam Trap - DN15 to DN50

Overview

The Spirax Sarco FT44 is a carbon steel bodied ball float steam trap designed for efficient condensate removal in industrial steam systems. Featuring stainless steel working internals and an automatic thermostatic air venting facility, this trap ensures reliable operation across a wide range of steam pressures and temperatures.

The FT44 is available in horizontal (FT44) and vertical (FT44V) flow configurations, with integrally flanged connections that allow maintenance without disturbing existing pipework. The body and cover castings are manufactured by a TÜV-approved foundry, ensuring compliance with stringent quality standards. The built-in BP99/32 thermostatic capsule handles superheat conditions up to 150°C at 0 bar g and 50°C at 32 bar g.

An optional manually adjustable needle valve (FT44-C) provides steam lock release (SLR) capability on horizontal versions, making this trap suitable for applications where air binding or steam locking may occur during start-up or intermittent operation.

Key Features

  • Carbon steel body (1.0619+N/WCB) with stainless steel internals for durability and corrosion resistance
  • Automatic thermostatic air venting for efficient air removal during start-up
  • Available in horizontal (FT44) and vertical downward flow (FT44V) configurations
  • Integrally flanged connections — maintainable without disturbing pipework
  • Optional steam lock release (SLR) needle valve on horizontal models (FT44-C)
  • Cover can be drilled and tapped 3/8" BSP or NPT for balance line connection
  • TÜV-approved foundry castings with PED compliance and CE marking
  • EN 10204 3.1 certification available on request
