Model 624 Flow Switch

The Delta Controls Model 624 is a target actuated flow switch and is equipped with a body that fits into and becomes part of the pipeline. The inside body dimensions and end connections are constructed to match those of the pipeline. This model is similar to Model 621 and is available in 1" to 8" sizes.

The Delta Controls Model 624 is equipped with a full swing target that rotates flush against the downstream body wall. This results in an open bore matching that of the pipeline.

The 624 is equipped with a flat blade type target that hangs down into the flow stream. In response to increasing flow rate; the switch actuates and the target rotates 90 degrees putting the target flush against the inside of the pipeline wall. The target is out of the way and the flow stream leaving the pipeline bore unobstructed. The flow velocity may be in excess of 100 feet (30 m) per second without damage to the body or target.
