Present air system relief valves require at least two moving parts, namely, a valve plate and a hinge plate for the valve plate. The pressure controlling component of the valve can be a spring which would be considered a third moving part. The spring would also require a spring mount. In some instances, an alternative pressure controlling component of the valve would be a predetermined amount of weight attached to the valve plate.
