Description
Model 417 is a coin-operated air vent with a 1/8″ NPT male connection for installation on water or steam radiators. It features special hygroscopic cellulose discs in the valve body. Its continuous cycle prevents radiators from becoming air-bound and speeds up the system’s filling. The Taco 417 coin vent is suitable for use in water (to 125 psi) and low-pressure steam (to 15 psi) applications. Its maximum operating temperature is 240°F.
