Description
Spirax Sarco FT14 float and thermostatic steam trap with a flanged connection, ductile iron body, and built-in automatic air vent. The flanged design allows in-line servicing without removing the trap from the pipeline.
Available Models
-
FT14(R-L): Horizontal connection with flow from right to left
-
FT14(L-R): Horizontal connection with flow from left to right
-
FT14(V): Vertical connection with downward flow
Other Options
-
FT14C: In addition to an air vent, includes a steam lock release device (SLR) to prevent steam locking in the system. The letter “C” is included in the model designation.
-
FT14X: Includes a built-in strainer.
Capsule
The BP99/32 capsule can be used with superheated steam, with superheat of 150°C@0 bar g and 50°C@32 bar g.
Standards and Certification
Complies with the European Pressure Equipment Directive 97/23/EC. An EN 10204 2.2 certificate is available when specified at the time of ordering.
