|
| |
|
Benefits & Features
Armstrong float and thermostatic traps are unique in their super heavy duty construction. Armstrong uses high quality ASTM A48 Class 30 cast iron or ASTM A216 WCB cast steel-normally found in pressure vessels rated to 250 psi (17 bar) or 465 psi (32 bar). Internal mechanisms are made from stainless steel and are heavily reinforced. No brass cotter pins here. Valves and seats are stainless steel, hardened, ground and lapped to withstand the erosive forces of flashing condensate. |

Armstrong's SH-1600 series bimetallic steam traps operate in superheat conditions. The SH Series steam traps operate by the effect that rising temperature has on the bimetallic elements. |
Armstrong's BMT Series bimetallic steam traps are suitable for superheat or low-load conditions. |
For pressures to 250 psig (17 bar)
Cold water capacities to 2,850 lb/hr (1,292 kg/hr) |
| |
|
|
|
Benefits & Features
Bimetalic Steam Traps have the ability to handle large start-up loads. As the system increases in temperature and pressure, the trap's stacked nickel-chrome bimetallic elements start to expand, allowing for tight shutoff as steam reaches the trap, thus preventing steam loss. |

DOT-7000 Series
Dual Orifice Steam Trap |
Dual Orifice steam traps are ideally suited for use on shipboard steam systems. The Dual Orifice steam trap is intended to perform with shipboard steam systems where steam is created from demineralized or purified water. The water used onboard does not contain minerals and impurities typically found in land-based steam systems.
|
Armstrong's DOT-7000 Series Dual Orifice steam traps are intended for condensate drainage applications recognizing a constant steam supply and return pressure, and also condensate loads that are not variable.
