Paint spray gun nozzle assembly

A pilot operated pressure relief valve for use on medium and high pressure vessels, conduits, and the like. A two-stage, non-flowing pilot valve operates a main relief valve of substantially greater capacity. In a preferred embodiment the main valve is mounted directly onto the pressure vessel which is to be vented at a predetermined pressure. The pilot is preferably mounted closely adjacent to the main valve for operating communication therewith. An improved main valve seal is provided which allows the use of commonly available seal configurations in a simple and easily assembled construction to provide a fast operating, high pressure seal.
