• 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
• Can also be manually shut-off
• 125 psi maximum discharge pressure
• Non adjustable, straight mount, float style
