Chemical Injection Quill With Isolation Valve

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

AC-VEI 11219 Chemical Injection Quill Introduction

The AC-VEI 11219 injection quill is designed to be inserted into a process to allow a chemical reagent to be injected directly into the centre of a pipeline. With an integrated isolating ball valve the injection quill can be easily withdrawn from the process pipework for cleaning or maintenance.

The AC-VEI has a 1/2" BSP process connection to allow simple integration into pipework. Manufactured in PVC with a choice of seal and O-ring materials to ensure a wide range of chemical compatibility.

The maximum insertion length of the AC-VEI 11219 is 175mm ensuring that it's compatible with pipework measuring up to 14" Ø to give a centralised dose of chemical reagent.

For smaller pipework installations, the AC-VEI 11219 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 11219 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The isolation valve means that the injection quill can be quickly withdrawn from the process pipework and process flow can be isolated.

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 11219 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 without the isolating ball valve - please see the AC-VEI 11377.

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 11219 Features & Benefits

The AC-VEI 11219 is a PVC injection quill is of proven design for a long operational life span. In processes where cleaning or periodic maintenance is required the AC-VEI 11219 includes an integrated isolation valve. This allows the injection quill to be withdrawn from the process for cleaning and maintenance while the process pipework is isolated.

The non-return valve allows the injection quill to remain in operation without the process chemical returning back through the injection quill and into the dosing tube.

With a maximum length of 175mm the AC-VEI 11219 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 11219 is compatible with most dosing pump types.

With wetted parts in PVC and a choice of seal and O-ring material the AC-VEI 11219 is compatible with a wide range of chemical reagents.
