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.

Air-Pulse Flow Control Valves for Filter Cleaning
Designed for use in dust-collection systems, these normally closed diaphragm valves periodically burst air to knock debris from filters. Connect the valve’s inlet port to your air supply, and connect the outlet port to the blow tube in your system.
A solenoid is required to actuate the valve.
Flow coefficient (Cv) is a measurement that indicates how much airflow a control valve can provide to your cylinder.

Rapid Air-Pulse Flow Control Valves
These valves convert a continuous stream of air into a series of rapid pulses, reducing air consumption by up to 50% and improving performance in air blowing applications such as cleaning and drying.
Valves with air-pilot actuation activate when they receive an air signal. Valves with electric (solenoid) actuation activate when voltage is applied to the electrical connection.
Normally closed valves normally block flow, remaining closed until actuated. Normally open valves normally allow flow, remaining open until actuated.
Flow coefficient (Cv) is a measurement that indicates how much airflow a control valve can provide to your cylinder.
