417 Coin Vent
Installed on water or stream radiators the Taco automatic coin vent is the ideal air purging device. The coin
vent features special hygroscopic cellulose discs in the valve body. When dry the discs allow air to be released
from the system. Once all the air is purged the discs would then come in contact with system water, where
upon they would swell to create a positive shut-off. This continuous cycle prevents the radiators from becoming
air bound and speeds the process of filling the system. The vent can also be manually shut-off by means of an
internal ball check. The 417 coin vent is suitable for use in water and low pressure steam applications.
Hy-Vent
®
The Taco Hy-Vent
®
has become the industry standard for dependable long life service. Available in 1/8”, 1/4” and
1/2” x 3/4” threaded connections, the high capacity float style vents can be placed either on the boiler or at the
high points throughout the system. Now with operating pressure ratings of up to 250 psi, the brass body, nickel
plated vents meet the system requirements of even the largest installation. The vents are also easily serviceable
if needed, by just unscrewing the vent cap.
409 Vent
The Taco 409 air vent is a heavy duty brass vent rated to 150 psi system operating pressure. The conical shape
of the vent significantly increases the clearance between the water level and internal mechanisms, reducing the
potential that dirt floating on the top of the water could foul the venting operation. It features a convenient
outlet connection for a 3/4” ID flex tube waste connection. It’s high capacity design makes it ideal for placement
throughout commercial systems.

Waste Connector
The Hy-Vent
®
Waste Connector screws onto the outlet connection of the Hy-Vents (models 400, 426, 418, 416)
to provide a worry-free installation. The 1/4” threads easily connect to a waste line, preventing water damage
if the vent ever leaks.
