These mixers have unthreaded ends that can be secured with compression or push-to-connect fittings. Materials mix as they pass over the fixed spiral blades. They require no external power source.

Also known as injection quills, use these in applications where the line can be shut down to perform maintenance and cleaning.

A ball valve allows you to isolate the flow to minimize spillage. Outlet tubes can be removed for maintenance and cleaning without shutting down the line. To remove the tube from the pipe, loosen the compression fitting and retract it until the limit chains are taught. Then, close the ball valve and unhook the limit chains. There may be spillage if the process pipe is under pressure.
