About Flow Control Valves
Also known as cylinder speed controls, flow control valves let you control the extension or retraction speed of your air cylinder. They regulate airflow as it passes from the valve's inlet to its outlet. Air flows freely in the opposite direction.

Inline Air Flow Control Valves
Designed to be mounted inline, these valves can be installed in an easy-to-reach location along your line. 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. 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). 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.
NPTF (Dryseal) threads are compatible with NPT threads.
Valves with push-to-connect ports are for use with plastic or soft metal tubing. Insert tubing into the port. Valves with barbed ports are for use with soft plastic or rubber tubing; insert the barbed port into the tubing.
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.

Inline Corrosion-Resistant Air Flow Control Valves
Made of stainless steel and plastic parts, these valves are more corrosion resistant than valves made of brass, aluminum, or zinc. They control the speed of air-powered equipment by adjusting the volume of airflow. Use them to 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). They’re designed to be mounted inline, allowing you to install them 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 between the cylinder and the valve. Insert plastic or soft metal tubing into the push-to-connect ports.

Two-Action Electrically Operated Air Directional Control Valves
Also known as 4-way and 5/2 valves, these valves create two actions, such as extending and then retracting a double-acting cylinder. Apply voltage to the electrical connection to actuate. They direct airflow from the inlet to your equipment and exhaust return airflow to create motion. Return actuation is by spring, so they return to their original position as soon as voltage is removed.
Flow coefficient (Cv) is a measurement that indicates how much airflow can pass through a valve.

Input-Selecting Air Directional Control Valves
Also known as shuttle valves and "or" valves, these valves select between the higher of two inlet pressures to power one outlet port. They're often used in emergency systems where the lower pressure input acts as a backup to the higher pressure input.

Inline Air-Release Valves for Water
- Max. Pressure: 125 psi
- Temperature Range: 40° to 240° F
Eliminate air pockets without stopping flow—these valves have an internal wire brush that traps air bubbles and discharges them through the top relief port while allowing inline flow from the inlet to the outlet. They are often used to increase efficiency in heating and cooling systems. The vented relief port exhausts discharge directly. Valves have a durable bronze body for a long service life.
