Armstrong 30-A, AI 1 in NPT Float & Thermostatic Steam Trap

Armstrong's A and AI Series float and thermostatic steam traps serve industrial applications from 0 to 175 psig and use a balanced-pressure phosphor-bronze bellows caged in stainless steel. They suit heat exchange equipment that must vent air and non-condensable gases quickly. The AI Series adds in-line connections with the same internals as the A Series.

Part D502445 is the Armstrong 30-A, AI in 1 in NPT.
