Inside COMFIT Relief Valves: general characteristics

COMFIT USA / Hollywood, FL / October 2nd 2023

Relief valves are among the most crucial safety valves. They are designed to limit the pressure within a system by releasing it to the atmosphere when the system’s pressure exceeds a set limit. This is accomplished using a spring set to a specific tension, known as the set pressure. The set pressure is the minimum pressure at which the valve will start to open should the system pressure exceed the designated limit.
