Beschreibung
Zusammenfassung:	A pressure relief system and a non-intrusive, low chatter pressure relief valve for use with such as system are disclosed. The pressure relief valve allows excess pressure in a pressurized fluid line to flow through a flow return line to a fluid reservoir when the fluid pressure exceeds the valve's pressure limit setting. The establishment of a uniform channel between the valve stem and the inner surface of a housing in which the valve stem is slidably located, as well as the use of a vent and sight tube to remove air from the top portion of the housing upon a spring being compressed during the opening of the valve, reduces the occurrence of pulsation and vibration when the valve is cycled between its open and closed positions. When the valve is in its closed position, the bottom end of the valve stem is in close proximity to the inner surface of the main fluid passageway in the pressurized fluid line, but does not intrusively interfere with the flow of fluid through the main fluid passageway.
