Hoffman 401440 Radiator Steam Vent Air Valve

Hoffman 401440 Radiator Steam Vent Air Valve is a float-type radiator vent designed to automatically release trapped air from steam heating systems, helping sustain steady steam flow and warm radiators quickly. Built for durable performance in demanding piping environments, this vent minimizes air locks and reduces noise, contributing to overall system efficiency and comfort.

Designed for precise, reliable operation, the vent features a 1/8 inch inlet size with a threaded angle inlet connection. The non-adjustable port ensures consistent venting without field calibration, while a 6 PSIG operating pressure and 10 PSIG maximum pressure rating provide safe, dependable performance in typical steam applications across radiant heating piping systems.

Ideal for radiators and steam-only piping networks, this valve offers robust construction and straightforward installation, delivering continued air discharge as steam fills the system.
