SH-2000 Series Superheat Traps


Bimetallic steam traps for superheat conditions

For pressures to 400 psig (28 bar) . . .
Cold water capacities to 4800 lb/hr (2175 kg/hr)

SH Series Superheat Steam Traps operate by the effect that rising temperature has on the thermostatic bimetallic elements.

The effect of rising temperature on bimetallic elements operates the
Armstrong SH-2000 bimetallic steam trap. It adjusts to changing
conditions because the curving of the bimetallic elements, caused by
increasing temperature, compensates for increasing pressure.

At start-up, the valve is wide open, which allows a large volume of
non-condensables and cold condensate to be removed from the system. When
the system reaches steam temperature, the elements become sufficiently
hot to pull on the trap’s valve stem, closing the valve.

The valve remains closed until the bimetallic elements cool, thus
allowing the valve to crack open, venting the condensate and
non-condensables, and then close again when steam temperature is

The Armstrong SH-2000 has a sealed, stainless steel body that is
lightweight, compact and highly resistant to corrosion. It is adaptable
to an Armstrong 360° Universal Connector or a Trap Valve Station (TVS).
This makes it easy to install and replace, as the trap can be removed
while the connector remains in-line. That means savings in labor cost
and ultimate flexibility—because inverted bucket, thermostatic,
thermostatic wafer, disc, and float and thermostatic steam traps can all
be installed on the same connector.
