Why Choose Armstrong F&T Steam Traps?
Armstrong International is a globally recognized leader in steam system solutions. The Series A F&T steam trap combines a buoyancy-driven float valve with a thermostatic bellows element to deliver continuous, modulating condensate discharge while simultaneously venting air and non-condensable gases. This dual-action mechanism helps maintain optimal heat transfer efficiency, reduces energy waste, and protects downstream equipment from the damaging effects of water hammer and air binding.
