QB-316-050, 1/2" MNPT Stainless Steel Injection Quill.
Type 316 Stainless Steel are suitable for high pressure, high temperature applications. Simple to use ½” MNPT male process connection and ½” MNPT male chemical inlet connection. The QB series injection quills come with a built-in check valve to prevent back flow of water or steam through the nozzle and into the chemical line. The crack pressure (amount of psi required to open the check valve) on the QB series of injection quills is 20 psi. All of the Eddington injection quills come with two machined flat surfaces on external portion of nozzle so a wrench can be used during installation. The QB injection quills come with the telltale V notch and witness mark to ensure proper nozzle alignment with process steam for proper dispersal of injected chemical. Standard quill length is 2 3/4″ long but custom lengths up to 24″ are available. For additional lengths please add the quill length desired to the end of the Eddington part number (e.g. QCFM-316-050-18). Made in the USA Click here for data sheet
