Eclipse 501226 6Bv-Ab 1 1/2 Inch Valve

The Eclipse 501226 6Bv-Ab is a 1.5-inch automatic full-port butterfly valve intended for use in air conditioning systems. The flow of water or air is controlled in applications such as heating, ventilation, and air conditioning. This particular style of butterfly valve, in contrast to certain others, has a full-port design, which reduces pressure drop and increases flow efficiency by matching the diameter of the pipe opening through the valve. A revolving disc that pivots inside the housing of the valve regulates flow. When the disc is open, it lines up with the pipe to provide free flow. The disk can be rotated in a way that restricts or closes the flow route entirely. For automated control, this automatic version probably has an actuator or motor connected to the disc; it might also be coupled with building management systems.
