Pressure relief valves, also known as safety relief valves or pressure safety valves, are designed to protect vessels or containers during an overpressure event while transferring liquids or gases. An overpressure event happens when pressure increases inside an enclosed container packaging or equipment beyond the specific or maximum working pressure level.

Valves protect containers by releasing gas from the over-pressurised enclosed container or equipment by releasing excess vacuum and pressure from the system. Engineered using high-quality, durable, and resilient materials catered to industrial and military standards, the valves prevent accidents caused by dangerous levels of pressure build-up within the equipment or systems. They relieve excess pressure in the system and prevent any damage or accidents caused by over-pressurization.
