Armstrong liquid drain traps deploy the same lever mechanisms, valves, and seats as inverted bucket traps. These liquid drain traps are used to drain liquids from most gases, for example water from compressed air. The trap removes the water and prevents the escape of air. Liquid drain traps are available for service pressures up to 1000 psi. Models available in both cast iron body and stainless steel body construction. Armstrong liquid drain traps feature an elliptical float and high leverage, which make it possible to open large orifices to provide adequate capacity for drain trap size and weight.
