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.

These valves handle pressure up to 265 psi. They control the speed of air-powered equipment by adjusting the volume of airflow entering or exiting.

Adjust airflow equally in both directions. These valves regulate the speed of airflow as it enters and exits equipment. They're often used to control the extension and retraction speed of an air cylinder at the same time.

Protect air-powered equipment in emergency shut-off situations—when system pressure drops, these valves automatically close to stop cylinder motion, even at mid-stroke. They control the speed of air-powered equipment by adjusting the volume of airflow entering or exiting.

Control the flow of exhaust air while also regulating the exhaust air speed. These valves dump exhaust air to the atmosphere without routing it back through a directional control valve. The 90° elbow shape allows you to install them in tight spaces. Also known as quick exhaust valves.

Quickly dump exhaust air to the atmosphere without routing it back through a directional control valve to speed up the movement of equipment. Also known as quick exhaust valves.
