  2. Breather Valves

Breather valves also referred to as direct-acting vacuum or pressure relief valves, are designed to protect enclosed containers from excessive pressure or vacuum build-up. The valves are available in multiple configurations, including vacuum-only, pressure-only, or dual-pressure, and provide choices between flanged or atmospheric vented outlets.

Extensively employed in bulk containers and tanks to minimise evaporation losses, the valves effectively use spring and pallet systems to regulate pressure and vacuum levels. Our catalogue of breather valves is designed to cater to different applications and ensure the protection of large-capacity storage containers.
