The Vesda VSP-974 is a replacement rotary valve for the VESDA VEA addressable aspirating detector. The VEA samples each microbore tube in sequence. The rotary valve directs airflow through that sampling process. Therefore, it is central to address-by-address sampling.
Vesda VSP-974 rotary valve function
First, the VEA draws air from many sampling points. Then the rotary valve selects each point in turn. As a result, the detector can identify which sampling point sees smoke. Over time, this moving part may require replacement during maintenance.
Ordering notes
Confirm that your detector is a VESDA VEA unit before ordering. Also, keep a spare valve to limit service downtime. This part ships as a genuine VESDA VEA replacement component. For fitment guidance, follow the VEA service documentation.
