Spirax Sarco FTGS14 Ball Float Steam Trap
The Spirax Sarco FTGS14 ball float steam trap uses stainless steel construction for continuous drainage duties where corrosion resistance and compact installation are important.

Spirax Sarco FT43 Ball Float Steam Trap
The Spirax Sarco FT43 ball float steam trap is a model-specific product path for users searching for FT43, FT43-10 or FT43V selection information inside the cast iron flanged ball float trap range.

Where FT43 sits in the range
FT43 is the direct route for users who already know the model and do not want
to land on a broad ball float steam trap family page. It is especially relevant
for searches such as Spirax Sarco FT43, FT43-10 Spirax Sarco and installed
base enquiries where the immediate question is whether the project still fits
the FT43 cast iron flanged route.
Within the current product documentation, FT43 is documented separately for
DN25-DN50 and DN80-DN100 sizes. That gives enough model-specific context to
support a dedicated FT43 product page rather than treating every FT-series query
as a generic category search.
Product facts
The FT43 product documentation confirms these selection boundaries:
FT43is a cast iron ball float steam trap with integral automatic air venting- the documented connection route is flanged
- current documents cover
DN25,DN40,DN50,DN80andDN100 - the FT43 pressure classes are documented as
FT43-4.5,FT43-10andFT43-14 FT43Vis the vertical-down flow variant for the documented smaller sizesFT43-Cadds a manually adjustable needle valve for steam lock release where specified
When FT43 is worth checking first
FT43 is usually worth checking first when the installation calls for a flanged cast iron ball float trap, continuous condensate discharge and strong automatic air venting during start-up. That makes it a practical route for heat exchangers and process plant where condensate back-up would affect heat transfer, temperature stability or product quality.
If the enquiry is broader than a single model, start with the ball float steam traps family page. If the project is still comparing operating principles, review mechanical steam traps before narrowing the selection.
What to confirm before final selection
- whether the required route is the standard FT43, FT43V or FT43-C option
- which documented size and flange standard match the installation
- whether the duty aligns with the
4.5 / 10 / 13 bardifferential-pressure classes - whether the pipework orientation matches the documented horizontal or vertical-down route
- whether local documentation, certification or spare-part requirements need review before ordering

Continue your FT43 selection route
FT43 enquiries usually start with a known installed model, but final selection still depends on size, orientation, pressure class and the surrounding steam application.
Compare the FT trap family
Return to the wider ball float steam trap range when FT43 needs to be compared with FT14, FT44, FT46, FT47 or other continuous-drainage trap routes.
Check the operating principle first
Review mechanical steam trap operating principles when the duty still needs confirmation that ball float drainage is the right trap type.
Connect FT43 with application selection
Use the selection example when the installation still needs application-level checks around condensate load, start-up venting and stall risk.
