Chemical injection quills ensure that chemicals are evenly dispersed into the center of the pipeline, which prevents channeling of the chemical down the pipe wall. The quils are equipped with a removable check valve to prevent the medium (or boiler water) to flow back to the dosing tank and to give the necessary back pressure to the pump.
- Different back pressure values of check valves available
- NPT threaded connection.
- Stainless steel 316 or higher grade material.
