Description
The function of the radiator air vent is to provide a means for air to be driven out of the radiator as steam enters. At a given pressure the fill time of a radiator varies proportional to its heat capacity and inversely proportional to the venting capacity of the radiator air vent. It is possible to control the speed at which a radiator will fill with steam by installing a radiator air vent with a certain venting capacity. Used in this manner, radiator air vents are helpful in evening out the heat distribution in a building.
• Exclusive Fingertip Adjustment: Simply sliding a lever allows you to adjust the venting rate.
• Each Radiator Has Its Own Venting Speed: In hard to heat areas, the radiator VARIVALVES® can be adjusted for
quicker venting. In overheated areas, the VARIVALVES® can be adjusted for slower venting. This allows steam to be
evenly distributed in the system.
• Long Term Fuel Savings: Because Heat-Timer VARIVALVES® vent more quickly, it takes less time to fill your
system with steam. By adjusting the venting to balance the system, there is no need to raise the steam pressure to
reach under heated areas. Shorter boiler runtimes and lower pressure results in fuel savings.
• Replace Valves with VARIVALVES: Using Heat-Timer adjustable vent rate VARIVALVES® throughout the
system allows you to balance the heat to your requirements
