Relief Valves and Vacuum Breakers - Apollo Valves

Relief valves and vacuum breakers are vital safety devices that protect systems and equipment from overpressure or vacuum conditions. Relief valves are designed to automatically relieve excessive pressure within a system, preventing potential damage or catastrophic failure. They are commonly used in boilers, pressure vessels, pipelines, and hydraulic systems. On the other hand, vacuum breakers are utilized to prevent the formation of a vacuum or negative pressure within a system, which can lead to implosion or damage. Vacuum breakers are commonly found in plumbing systems, water supply lines, and industrial processes. These valves ensure system integrity and safety by releasing pressure or preventing vacuum, safeguarding equipment, and preventing potential hazards.
