This animation I created breaks down the basic function of the three-way valve, and a relief valve opening.

Pressure relief valves play a critical role in various industries, serving as a safeguard against the over-pressurization of vessels or equipment. These valves are designed to open automatically when the pressure inside a system reaches a predetermined set point, thus reducing the pressure and preventing catastrophic failures.

In a dual-pressure relief valve system, a 3-way valve is often utilized to redirect the flow to the other relief valve. This helps to ensure that there is always a functional relief valve in operation, even when one valve needs to be replaced or undergo maintenance. By redirecting the flow, the 3-way valve helps to maintain the safety and reliability of the system.
