Introduction

The Cummins 3279323 Pressure Relief Valve is engineered to manage and regulate pressure within heavy-duty truck systems, ensuring pressure levels remain within safe operating limits. This contributes to the efficient and reliable performance of the truck, maintaining system integrity and preventing potential damage from excessive pressure.

Basic Concepts of Pressure Relief Valves

A Pressure Relief Valve is a safety device that automatically releases excess pressure from a system to prevent over-pressurization. It operates by opening when the pressure exceeds a predetermined set point, allowing fluid or gas to escape until the pressure is reduced to a safe level. These valves are commonly used in hydraulic, pneumatic, and fuel systems to protect equipment and ensure safe operation ¹.
