In order to free a seized valve, an inspection port is formed in a wall of the valve body and the areas where the valve is seized are determined. One or more injection ports are formed in the valve body adjacent to the seized portions of the valve, pressurized fluid (preferably an insoluble lubricant having a very high cone penetration) is injected through the or each injection port and the injection ports are then closed.

The atomizer assembly of claim 5, wherein said elongate member comprises medical grade tubing having a diameter of about 1/8 inches. 7. The atomizer assembly of claim 5, wherein: said plug is received within a bore in said body; said plug assumes a first deformed configuration during assembly to said elongate member; assumes a second deformed configuration when fluid is forced under pressure past said plug for discharge through said exit orifice; and returns to said first deformed configuration when pressure is sufficiently reduced on said fluid; and movement of said plug from said second to said first deformed configuration retracts fluid at said exit orifice back into the interior of said nozzle, whereby to help maintain a dry nozzle tip exterior. 8. The atomizer assembly of claim 1, wherein: said nozzle comprises a tip element defining a forward portion of a swirling chamber having inlet ports and an exit orifice; and a post, affixed to body structure of said nozzle, is configured and arranged on assembly with said tip element to define a rear portion of said chamber. 9. The atomizer assembly of claim 8, a proximal end of said nozzle being constructed and arranged for connection to said elongate member comprising a medical grade tubing having a diameter of about 1/8 inches. 10. The atomizer assembly of claim 9, said nozzle consisting of a two piece assembly. 11. An atomizer comprising: a body having a distal interior surface defining a forward portion of a swirling chamber having inlet ports and an exit orifice; a plug housed within said body, said plug having a distal end defining a rear portion of said chamber; and a fluid delivery conduit having a distal end with an entrance orifice disposed at a proximal end of said plug; wherein said plug is resilient to deform and create a self-bias with said proximal plug end being configured and arranged to occlude said entrance orifice and resist inadvertent discharge of a fluid therethrough, but wherein deliberate pressurization of said fluid causes said plug to deflect sufficiently to permit discharge of said fluid through said entrance orifice. 12. The atomizer of claim 11, further comprising a fluid ring disposed upstream of said inlet ports to promote uniform fluid flow into said inlet ports. 13. The atomizer of claim 11, wherein: said fluid delivery conduit is a passageway in an elongate tubular member; said plug assumes a first deformed configuration during assembly of said body to said elongate member; assumes a second deformed configuration when fluid is forced under pressure past said plug for discharge through said exit orifice; and returns to said first deformed configuration when pressure is sufficiently reduced on said fluid; and said plug and said chamber are sized in harmony such that movement of said plug from said second to said first deformed configuration retracts fluid at said exit orifice back into an interior of said body, thereby maintaining a dry nozzle tip. 14. The atomizer of claim 11, wherein the pressure required for discharge of a fluid is greater than about 5 psi. 15. The atomizer of claim 11, further comprising: an elongate tubular member having proximal and distal ends with said fluid delivery conduit being disposed therebetween, a proximal end of said body being attached at said distal end of said elongate member; wherein said self-bias of said plug is created by trapping said plug in compression between structure of said body and a forward end of said elongate member. 16. The atomizer of claim 15, wherein said elongate member comprises medical grade tubing having a diameter of about 1/8 inches. 17. The atomizer of claim 15, further comprising: a plurality of conduits disposed between said first and second ends of said elongate member; and a malleable wire disposed in one of said conduits and
