Abstract
A pressure relief assembly may include an actuator stem having a plurality of retaining grooves. A relief plate may be operatively connected to the actuator stem and a diaphragm plate may be operatively connected to the actuator stem. A diaphragm may be least partially disposed between the relief plate and the diaphragm plate. A relief spring seat may be releasably attached to the actuator stem at one of the plurality of retaining grooves. The relief spring may be adjusted by moving the attachment point from one retaining groove to another retaining groove.
