Armstrong International 175A8 2" Float & Thermostatic F&T Steam Trap 175 PSI

The Armstrong International 175A8 is a 2" cast iron float and thermostatic (F&T) steam trap rated for 175 psi. It is also known as the 175-A8 or A8-175 steam trap, and belongs to the Armstrong A Series. It is built for industrial service on heat exchange equipment, where air and non-condensable gases must be vented quickly.

Key Features:

• Float and thermostatic design for continuous condensate drainage with built-in air venting
• 2" NPT screwed connections in a same-side inlet and outlet configuration
• Cast iron body (ASTM A48 Class 30) for horizontal installation
• Maximum allowable and maximum operating pressure of 175 PSIG (12 bar)
• Maximum allowable temperature of 377°F (191°C)
• 17/64" orifice
• Capacity of up to about 7,200 lb/hr (3,265 kg/hr)
• Balanced-pressure phosphor-bronze bellows caged in stainless steel for the thermostatic air vent
• Armstrong part number D500448

The trap handles modulating pressures and widely varying loads. It also vents air well at very low pressures, copes with start-up air loads, and works against back pressure.
