Inject Quills for safe delivery of chemicals into pipelines

Blacoh SENTINEL Injection Quills are used to provide safe delivery of chemicals into pipelines. The quill end ensures the dispersion of the chemicals away from the pipe wall. The integral spring loaded check valve prevents backflow from the pressurized pipe if there is a break in the discharge piping. A union connection on the inlet allows for ease of installation and maintenance.
