LS/MS Series Float & Thermostatic Steam Traps

Cast steel for horizontal installation, with thermostatic air vent

For pressures to 450 psig (31 barg) . . .
Capacities to 280 000 lb/hr (127 000 kg/hr)

The simple, yet rugged, cast steel construction of the LS & MS Series Ultra-Capacity F&T steam traps offer long, trouble-free service. All floats, valves and seats, and lever mechanisms are constructed of stainless steel.

The integral thermostatic air vent is a balanced-pressure phosphor-bronze bellows caged in stainless steel. It is designed especially for demanding industrial applications where highly efficient, uninterrupted service is essential. This balanced-pressure type of air vent will respond to the pressure-temperature curve of steam at any pressure from zero to 250 psig (17 bar). Thus-up to 250 psig (17 bar)-air is vented at slightly below steam temperature.
