Carbon Steel
Ball Float Steam Trap (DN15 and DN20)
FTC32-C
FTC32CV shown
The FTC32 is a carbon steel ball float steam trap with integral
automatic thermostatic air vent. It is ideal for all process drainage
applications as condensate is always removed efficiently and
quickly over a wide range of fluctuating pressure and load
conditions. Standard connections are horizontal from right to left
(R-L) when viewed from the base.
Capsule
The BP99/32 capsule which is used in the FTC32 ball float steam
trap is suitable for use on 150°C superheat @ 0 bar g and 50°C
superheat @ 32 bar g.
Standards
This product fully complies with the requirements of the European
Pressure Equipment Directive 97 / 23 / EC and carries the CE mark
when so required.
Certification
This product is available with certification to EN 10204 3.1.
Note: All certification / inspection requirements must be stated at
the time of order placement.
Sizes and pipe connections
½" and ¾" screwed BSP and NPT.
½" and ¾" socket weld to BS 3799 Class 3000 and
ASME (ANSI) B16.11 Class 3000.
DN15 and DN20 flanged to EN 1092 PN40,
ASME (ANSI) B16.5 Class 150 and 300, JIS/KS 20K and 30K.
Optional extras
The FTC32 is also available with horizontal connections having
flow from left to right - FTC32 (L-R), and vertical flow both
downwards and upwards - FTC32V.
The trap is available with either ASTM or DIN body material.
An optional manually adjustable needle valve can be fitted to all
versions which provides a steam lock release feature in addition
to the air vent - FTC32-C.
An optional internal strainer screen is available - FTC32X.
An internal non-return valve is available - FTC32CV.

Capacities
Condensate kg / h
Differential pressure bar ( x 100 = kPa )
Additional cold water capacities from thermostatic air vent (TV) under start-up conditions.
Capacities shown above are based on condensate at saturation temperature. Under start-up conditions when the condensate is cold the
internal thermostatic air vent (TV) will be open and provides additional capacity to the main valve. The following table gives the minimum
additional cold water capacities from the air vent.
