Designed to be mounted inline, these valves can be installed in an easy-to-reach location along your line. They control the speed of air-powered equipment by adjusting the volume of airflow.

A fine-adjustment dial allows tighter control of airflow and cylinder speed than other flow control valves. They control the speed of air-powered equipment by adjusting the volume of airflow entering or exiting.

A numeric indicator provides a relative measure of airflow, similar to the volume dial on a speaker, so it's easy to set the same flow rate with each use. Mount them directly to cylinder ports, eliminating additional tubing between the cylinder and valve for better control than inline valves. They control the speed of air-powered equipment by adjusting the volume of airflow.
