Hoffman Specialty
Steam Radiator Air Vent, 1/8 Inch Angle, Non-Vac
Detailed Description
A steam radiator air vent designed for use in low‑pressure, one‑pipe steam heating systems. This float‑type air valve automatically releases trapped air from radiators, allowing steam to circulate efficiently and ensuring even heat distribution throughout residential and commercial spaces. Featuring a 1/8 inch NPT angle connection, the vent is compact and easy to install on standard radiator tappings. Its float‑actuated design opens to discharge air during system startup and closes when steam reaches the vent, preventing steam loss and maintaining system efficiency. It is equipped with a single, non‑adjustable port, making it ideal for systems that do not require proportional venting control. It is designed to operate at pressures up to 6 PSIG, with a maximum pressure rating of 10 PSIG, making it suitable for typical low‑pressure steam heating applications.
