Thermodynamic Steam Traps

DESCRIPTION:
Thermodynamic steam trap without integral strainer.
Compact, light weight design, in full stainless steel
(SS 316 L ) construction.

FEATURES:
Better corrosion and wear resistance ensured by the
total stainless steel construction.
It meets the requirements of quick response
applications in the steam system.
Condensate entry below the disc, concentric to the disc
/ seat ensures a clean and parallel lift of the disc with
reference to the seat, eliminating localized wear and
tear.
Ideal for fluctuating loads and pressures.
Perfect shut-off, no steam loss.

SIZES: NPS DN 8, 10, 15, 20, 25
CONNECTIONS: Screwed (NPT/BSPT/BSP)
Socket weld
Non IBR1 / IBR approved

LIMITING CONDITIONS:
PMA: Max. allowable pressure
TMA: Max. allowable temp.

16 bar(g)
450 ºC

Maximum operating back pressure at the outlet should not
exceed 80% of the inlet pressure.
Minimum differential pressure for
satisfactory operation.

Cold hydro test pressure

0.25 bar
32 bar(g)

INSTALLATION:
The trap will operate in any position, but the preferred
installation is in the horizontal plane with the cap on the
top. Full port isolating valves should be installed
upstream and downstream of the trap for safe
maintenance. Always open isolation valves slowly until
normal operating conditions are achieved to avoid
system shocks.

MAINTENANCE:
The trap can be maintained without disturbing the
piping connections. Ensure that the trap is isolated upstream and downstream - before attempting to
dismantle it. ALLOW THE TRAP TO COOL BEFORE
DISMANTLING
Periodic cleaning of the disc and seat will facilitate
trouble-free performance. Do not use abrasive /
corrosive media for cleaning.
Only the disc and seat are subject to wear. A worn disc
can be replaced and slight seat wear can be corrected
by resurfacing on a lap plate.

IMPORTANT:
For new installations, the system should be properly
flushed prior to fitting the trap.
