What is the difference between a relieving and non-relieving regulator?

ControlAir relieving vs non-relieving regulator

Visually from the outside, there is usually no difference between a relieving and non-relieving regulator. Functionally there is a major difference. A relieving regulator can bleed pressure from downstream if the pressure rises above the setpoint, even in a no-flow condition. Normally this is done by a relief valve (or hole) in the center of the diaphragm and the pintle assembly. A large majority of pressure regulator applications use a relieving regulator.
