Steam Trap

Introduction

This installation sheet covers the installation and

maintenance of FTE Series Float and Thermostatic

Steam Trap.

Product Description

The FTE Series ball oat traps are tted with an

integral balanced pressure type thermostatic air went.

The FTE Series is available with horizontal in line

connections. However, in case of FTE-14 sizes

NPS 1/2 and 3/4 / DN 15 and 20, the position of body

can be changed to suit di󰀨erent ow directions like

left to right, top to bottom or right to left. A steam lock

release (SLR) option is available to FTE Series Traps.

WARNING

Personal injury, property damage,

equipment damage or leakage due

to escaping steam or bursting of

pressure containing parts may result

if this equipment is over pressured or

is installed where service conditions

could exceed the limits given in the

specifications or where conditions

exceed any ratings of the adjacent

piping or piping connections. To

avoid such injury or damage, provide

pressure-relieving or pressure-limiting

devices (as required by the appropriate

code, regulation, or standard) to prevent

service conditions from exceeding

those limits.

The maximum differential pressure (ΔP)

stamped on product name plate must

be greater than the maximum pressure

differential across the trap.

1. The pressure/temperature limits in this Installation Sheet and any applicable standard or code limitation should not be exceeded.

FTE Series Maintenance ▲ WARNING To avoid personal injury, property damage or equipment damage caused by sudden release of pressure or explosion of accumulated gas, do not attempt any maintenance or disassembly without first isolating the equipment from system pressure and relieving all internal pressure from the equipment. While working on steam traps consider the risk of getting burned, Therefore remember the following: • The piping parts before and after the steam trap must be atmospheric.
