Flair LR 100991-1 700 Series Solenoid Valve Timer

The Flair LR 100991-1 is a 700 Series Solenoid Valve Timer engineered for precise, repeating control of fluid flow in automated industrial systems. Upon power application, the timer enters an ON state (T1) for a user-adjustable duration, then switches OFF (T2) for a configurable period, cycling continuously until power removal. This repeat-cycle architecture delivers ±1% repeat accuracy and ±10% scale accuracy across selectable timing ranges, making it suitable for applications demanding consistent valve sequencing and flow regulation.
