Description

The FT14 is an SG iron bodied ball float steam trap having stainless

steel working internals and integral automatic air venting facility.

The FT14 can be maintained without disturbing the pipework.

Available types

Horizontal connections with flow from right to left

FT14 (L-R)

Horizontal connections with flow from left to right

Please note: On the cover of both of these traps, the orientation

of the connections can be adjusted on site in preparation of

downward vertical flow applications.

The BP99 / 32 capsule which is used in the FT14 is suitable for use

on 150°C superheat @ 0 bar g and 50°C superheat @ 32 bar g.

Optional extras

A manually adjustable needle valve (designated 'C' on the

nomenclature i.e. FT14-C) can be fitted to the trap. This option

provides a steam lock release (SLR) feature in addition to

the standard air vent. For further information please consult

Spirax Sarco.

The FT14 has the option of an integral strainer screen

(designated 'X' on the nomenclature i.e. FT14-X).
