FEATURES
  • 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
  • Large variable orifice
  • Phosphorus bronze bellows
  • Heavy duty construction and contemporary styling
  • High temperature O-ring seal
  • Seat and puppet at inlet to valve
DESCRIPTION

The venting capacity of radiator air vents and main line air vents used in single pipe steam heating systems has an important effect on the operation of these systems. In order to obtain a better understanding of these effects, The Center for Energy and Environment conducted experiments both in the laboratory and in the field to investigate the properties of single pipe steam air venting. Commercially available radiator and main line air vents were tested and compared. Main line air vents in one building were replaced with open pipe orifices of different sizes and the resulting fill characteristics of the main steam lines were observed. The purpose of the main line air vent is to rapidly vent the relatively large quantity of air in the main lines. This allows the main lines to fill more quickly and thus reduces the time difference of steam arrival at the different risers. A larger orifice allows the air to be pushed out at a lower back pressure.
