Injection Quill with Check - Eddington

The Eddington QB & QC Injection Quills offer MNPT process connections X MNPT pump side connections. These injection quills are available in Type 316 Stainless Steel, PVC, Kynar, Alloy 20, and Hastalloy C276.  The QC Injection Quill has a built in ball check valve to prevent backflow through the nozzle and into the chemical feed line. The QB Injection Quill has no check valve.  Crack pressure on the QC Injection Quill is 20 psi; if the pump cannot deliver at least 20 psi then a QC Injection Quill may be appropriate.  There are two flat surfaces on the external portion of the nozzle so a wrench can be used during installation.  Standard injection quill length is 2 ¾” but custom lengths up to 24” are available. For additional lengths please add the desired length after the part number (eg. QC-316-050-18).
