Abstract
A pressure relief valve having a modular design that allows the release pressure of the valve to be altered during assembly is provided by the present invention. The valve includes a serrated valve tube that fits inside of a valve body. A spring retainer ring fits on an outside diameter of the serrated valve tube such that it is held in position by interacting with the serrations. The release pressure of the valve is altered by changing the position of the spring retainer ring on the serrations. In addition, a variety of different spring types and configurations can be utilized in conjunction with the spring retainer ring position to select one of a large number of different release pressures for the valve during assembly.
