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.

With a PVC body and a fluoroelastomer seal that can withstand aggressive and corrosive solutions, these valves are often used in chemical-processing applications. Their ball-valve design provides higher flow rates than other air-driven valves. They operate on compressed air to automatically start and stop flow faster than motor-driven valves. You must control the air to the actuator using either the included electric pilot valve or a manual on/off valve (not included). These valves don’t require a minimum pressure drop between the inlet and outlet for operation. They are full port, so they do not restrict flow.
All have union fittings on each end that separate into multiple pieces for easy installation and removal from your pipeline. Valves come with both threaded NPT fittings and unthreaded socket-connect female fittings.
The actuator is secured to the valve body with a bracket for easy disassembly, maintenance, and repair. A visual flow indicator on the top of the actuator shows whether the valve is open or closed. All valves meet NSF/ANSI 61 and NSF/ANSI 372 Standards.
Single-acting actuators only require air pressure to open the valve; they automatically spring closed when the air turns off. These valves are normally closed unless actuated. Double-acting actuators require air pressure to open and close the valve. Once actuated, these valves remain actuated until air pressure is applied, so they do not have a valve starting position.
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.

Also known as diaphragm valves, these have a PTFE body and seals that stand up to harsh acidic solutions. The diaphragm can handle dirty liquid, slurries, and abrasive media without damage. All valves operate on compressed air to automatically start and stop flow. You must control the air to the actuator using either an electric pilot valve (not included) or a manual on/off valve (not included). These valves don’t require a minimum pressure drop between the inlet and outlet for operation.
All have a single-acting actuator that only requires air pressure to open the valve; they automatically spring closed when the air turns off. The actuator is directly mounted to the valve body to minimize movement and reduce wear. Valves are normally closed unless actuated.
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.

With a chemical-resistant fluoroelastomer seal and no metal parts to corrode, these valves are often used in chemical-processing and water-treatment applications. The lightweight actuator and compact body are designed for installation in any mounting orientation. All valves operate on compressed air to automatically start and stop flow. You must control the air to the actuator using either an electric pilot valve (not included) or a manual on/off valve (not included).

Air-Operated Air Flow Control Valves with Safety Shut-Off
Protect air-powered equipment in emergency shut-off situations—when system pressure drops, the air pilot 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 pilot 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.
Two direction valves control airflow as it enters (meter in) and exits (meter out) equipment, and are often used to control the extension and retraction speed of an air cylinder at the same time. One direction valves control flow as air exits the cylinder (meter out) and moves from the inlet to the outlet.
Valves with push-to-connect ports are for use with plastic or soft metal tubing. Insert tubing into the port.
Flow coefficient (Cv) is a measurement that indicates how much airflow can pass through a valve.
