Accelerators

The Reliable Model B1 Accelerator, equipped with an integral Accelo-Check anti-flooding device, is engineered to improve the operational speed of dry pipe and deluge valves in dry-type and pre-action automatic sprinkler systems.

By rapidly equalizing pressure and responding to minor fluctuations, the device supports faster system activation and can extend the number of sprinklers served by a single valve. Its compact, lightweight design, combined with self-adjusting capabilities and protection against water and debris intrusion, ensures reliable performance. The Model B1 Accelerator is tested for compatibility with Reliable dry pipe and pre-action systems.
