AC-VEI 11377

Chemical Injection Quill

PVC chemical injection quill manufactured in PVC complete with non-return valve.

Chemical injection quill manufactured in PVC with 1/2" BSP process thread, non-return valve and connections for either 4 x 6mm or 8 x 12mm dosing tube.

AC-VEI 11377 PVC Chemical Injection Quill Introduction

The AC-VEI 11377 injection quill is manufactured in PVC with a choice of seal and O-ring materials to ensure a wide range of chemical compatibility.

Designed to ensure that dosing pumps can deliver the chemical reagent in mid-stream, the AC-VEI has a 1/2" BSP process connection making it suitable for most pipework applications.

The maximum insertion length of the AC-VEI 11377 is 175mm, ensuring that it's compatible with pipework measuring up to 14" Ø and gives a centralised dose of chemical reagent.

For smaller pipework installations, the AC-VEI 11377 can be trimmed to the desired length and the non-return valve positioned at the installation point. The minimum acceptable length of the AC-VEI is 25mm making it suitable for use with 2" Ø pipework.

The AC-VEI 11377 includes an integrated non-return valve.  This prevents any of the process solution in the pipework from working it's way back into the injection quill to the dosing tube. When working with a non-return valve and with pipeline installations, it's important to ensure that the dosing pump can deliver against the pressure in the pipework.

The dosing tube is connected via a compression fitting at the rear of the injection quill and is suitable for either 4x6mm or 8x12mm dosing tube.

PVC Injection Quill Wetted Parts

The AC-VEI 11377 PVC injection quill is available with a choice of wetted parts to ensure greater compatibility.

The AC-VEI series are also available as an injection quill complete with isolating ball valve - please see the AC-VEI 11219.

The valve seats are available in either EPDM or Viton (© DuPont / Chemours) and we recommend checking our chemical compatibility database and your chemical supplier, to ensure that all the parts of the liquid end are compatible with the chemical to be dosed.

AC-VEI 11377 Features & Benefits

The AC-VEI PVC injection quill is of proven design to ensure that chemical reagents are dosed directly into the centre of a pipeline.

With a maximum length of 175mm the AC-VEI 11377 can be easily modified to shorten the length to 25mm for dosing into narrow pipework.

With a 1/2" BSP process connection and compression fittings suitable for 4 x 6mm or 8 x 12mm dosing tube, the AC-VEI 11377 is compatible with most dosing pump types.

The non-return valve on the injection quill is designed to prevent the process solution from travelling back through the injection quill and into the dosing tube.

With wetted parts in PVC and a choice of seal and O-ring materials, the AC-VEI 11377 is compatible with a wide range of chemical reagents.
