Heat-Timer 925005-00 Varivalve Angle Steam Radiator Vent, 1/8" NPT

Heat-Timer 925005-00 Varivalve Angle Steam Radiator Vent, 1/8" NPT

Varivalve Angle 925005-00 is an adjustable Radiator Air Vent with a 90 degree angle and 1/8" pipe thread, designed for a single pipe steam heating/venting. The lab and in-field trials clearly show that a larger vent can vent a system more rapidly resulting in lowering operating pressure requirements. Phosphor bronze bellows of 925005-00 Radiator Air Vent provides a positive shut-off by closing and stopping the steam from escaping the radiator once heated by steam otherwise the steam will not fill the radiator. The task of the Varivalve Angle 925005-00 radiator air vent is to drive out the air of the radiator before the steam entering. The fill time of a radiator changes proportionally to the venting capacity of the radiator air vent (at a given pressure). One can control the radiator steam fill time speed by simply installing a radiator air vent with a certain venting capacity. Varivalve Angle 925005-00 a Radiator Air Vent boasts quiet operation and is ideal for balancing out the heat distribution in a building. The convenient fingertip lever of Varivalve Angle 925005-00 provides the means of adjustment of the venting rate. The purpose of a larger orifice is to allow the air to be driven out at a lower back pressure.
