The Powergenex SAR Snap Acting Relay switches to an auxiliary air source when air pressure from the primary port falls below a predetermined level. This keeps the valve at its last position after loss of air.
As a fail-safe device with a fail-last function, it increases dependability of process control systems. It also accurately detects differential pressure and promptly provides snap-action.
This compact and lightweight snap acting relay has a rugged housing for tough working conditions. It comes in two types: single-acting (SAR-S) and double-acting (SAR-D).
