    Elbow Air Flow Control Valves

    Mount these valves directly to cylinder ports, eliminating additional tubing or piping between the cylinder and valve for better control and consistency than inline valves. Flow control valves control the speed of air-powered equipment by adjusting the volume of airflow. They control flow in one direction as air moves from the inlet to the outlet. Air flows freely in the opposite direction.
    Flow coefficient (Cv) is a measurement that indicates how much airflow can pass through a valve. When selecting between valves with the same port size, choose the valve with the higher flow coefficient to ensure it provides enough airflow to operate your system.

    Dual-Control Two-Direction Air Flow Control Valves

    Two knobs independently control airflow in each direction. These valves control flow in two directions as air moves from the inlet to the outlet and from the outlet to the inlet. They’re often used to control both the extension speed as flow enters a cylinder (meter in), and the retraction speed as flow exits a cylinder (meter out). For the best control, mount them as close to the cylinder as possible to minimize the length of piping between the cylinder and the valve.
    Flow coefficient (Cv) is a measurement that indicates how much airflow can pass through a valve.

    Install these valves in the exhaust ports of air directional control valves to control exhaust air speed without needing access to your cylinder. They control flow in one direction as air moves from the inlet to the exhaust port (meter out). Air flows freely in the opposite direction. Valves exhaust to the atmosphere and include a muffler to reduce the exhaust noise.
    Flow Coefficient (Cv)—Flow coefficient (Cv) is a measurement that indicates how much airflow can pass through a valve. When selecting between valves with the same port size, choose the valve with the higher flow coefficient to ensure it provides enough airflow to operate your system.

    Locking Handle—Locking handles have a nut to prevent accidental flow adjustment.
    Internal Check Valve—Internal check valves actuate when the pressure changes to stop flow from the controlled direction and allow free flow in the opposite direction. Valves with an internal check valve are often used to control the speed of air cylinders and air-powered motors.
    Flow Coefficient (Cv)—Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.

    High-Pressure Air Flow Control Valves

    These valves handle pressure up to 265 psi. They adjust the volume of air exiting an air cylinder (meter out) to control the speed of air-powered equipment. Use them to control flow in one direction as air moves from the inlet to the outlet. Air flows freely in the opposite direction. The inlet has a universal thread for connecting to NPT, NPTF (Dryseal), BSPP, and BSPT threads. Insert plastic or soft metal tubing into the push-to-connect outlet ports. The elbow shape allows you to mount them directly to cylinder ports, eliminating additional piping between the cylinder and valve for better control and consistency than inline valves.
    Flow coefficient (Cv) is a measurement that indicates how much airflow can pass through a valve. When selecting between valves with the same port size, choose the valve with the higher flow coefficient to ensure it provides enough airflow to operate your system.

    Single-Control Two-Direction Air Flow Control Valves

    A single dial adjusts the speed of airflow equally in both directions. These valves control flow in two directions as air moves from the inlet to the outlet and from the outlet to the inlet. They’re often used to control the extension speed as flow enters a cylinder (meter in), and the retraction speed as flow exits a cylinder (meter out) at the same time. For the best control, mount them as close to the cylinder as possible to minimize the length of tubing between the cylinder and the valve.
    Flow coefficient (Cv) is a measurement that indicates how much airflow can pass through a valve.

    Precision-Adjust Air Flow Control Valves

    A fine-adjustment dial allows tighter control of airflow and cylinder speed than with other flow control valves. These valves control the speed of air-powered equipment by adjusting the volume of airflow. They control flow in one direction as air moves from the inlet to the outlet. Air flows freely in the opposite direction. The elbow shape allows you to mount them directly to cylinder ports, eliminating additional tubing or piping between the cylinder and valve for better control and consistency than inline valves.
    Flow coefficient (Cv) is a measurement that indicates how much airflow can pass through a valve. When selecting between valves with the same port size, choose the valve with the higher flow coefficient to ensure it provides enough airflow to operate your system.

    Elbow Air Flow Control Valves with Flow Indicator

    A flow indicator on these valves provides a relative measure of the air flowing through the valve, from off to full volume, similar to the volume dial on a speaker. The indicator’s numeric increments make it easy to set the valve to the same flow rate with each use. These valves adjust the volume of air exiting an air cylinder (meter out) to control the speed of air-powered equipment. They control flow in one direction as air moves from the inlet to the outlet. Air flows freely in the opposite direction. The elbow shape allows you to mount them directly to cylinder ports, eliminating additional tubing between the cylinder and valve for better control and consistency than inline valves. Insert plastic or soft metal tubing into the push-to-connect outlet ports.
    Flow coefficient (Cv) is a measurement that indicates how much airflow can pass through a valve. When selecting between valves with the same port size, choose the valve with the higher flow coefficient to ensure it provides enough airflow to operate your system.

    Inline Air Flow Control Valves with Flow Indicator

    A flow indicator on these valves provides a relative measure of the air flowing through the valve, from off to full volume, similar to the volume dial on a speaker. The indicator’s numeric increments make it easy to set the valve to the same flow rate with each use. They adjust the volume of airflow to control the speed of air-powered equipment. Valves control flow in one direction as air moves from the inlet to the outlet. Air flows freely in the opposite direction. Typically, valves are installed to control flow as it exits the cylinder (meter out), but they may also be installed to control flow as it enters the cylinder (meter in). Designed to be mounted inline, they can be installed in an easy-to-reach location along your line. For the best control, mount them as close to the cylinder as possible to minimize the length of tubing or piping between the cylinder and the valve.

    Protect air-powered equipment in emergency shut-off situations—when system pressure drops, the air signal stops and these valves automatically close to stop cylinder motion, even at a mid-stroke. They control the speed of air-powered equipment by adjusting the volume of airflow. A pressure-release button allows you to exhaust any trapped air pressure from the system after shut down. Install them in pairs on cylinder exhaust ports, and use tee connectors (not included) to direct exhaust air from the cylinder to the air of the opposite valve, and to connect valves to a directional control valve. The elbow shape allows you to mount them directly to cylinder ports, eliminating additional tubing or piping between the cylinder and valve for better control and consistency than inline valves.
