Abstract
The present invention is directed to a technique of purging unwanted particles from the interior of a valve body. Inlet and outlet ports are formed in the valve housing to allow for circulation of the fluid within the valve body. The flow path of the fluid is isolated from the main fluid flow path when the valve is in the open or closed position. Additionally the pressure of the fluid is at a level higher than that of the main fluid flow.
