Free Floating Lever Air/Gas Vents—Forged Steel For Pressures to 1,000 psig (69 bar) or Specific Gravity Down to 0.40 High-Temperature Service Maximum allowable working pressures of floats decrease at temperatures above 100°F. Allow for approximately: • 10% decrease at 200°F • 15% decrease at 300°F • 20% decrease at 400°F The float is not always the limiting factor, however. Consult with Armstrong Application Engineering if you have a high-temperature application that also requires maximum operating pressures. Forged steel and stainless steel traps can be modified to resist hydrogen sulfide...
