Air Flow Control Valves

Parker flow control valves are designed to regulate the flow rate and pressure of media through a pipeline.

Air flow control valves.

Air piloted flow controls. Also known as 4 way and 5 3 closed center valves. Elbow air flow control valves mount these valves directly to cylinder ports eliminating additional tubing between the cylinder and valve for better control than inline valves. This makes independent speed control of different cylinders a breeze.

That being said most people won t need that tight control and these valves work great. They ship with an integrated pilot check valve as well as a temporary intermediate stop dial. These valves close all ports in the off position to stop equipment in a locked position with air pressure holding it in place. These valves close all ports in the off position to stop equipment in a locked position with air pressure holding it in place.

The elbow shape allows you to mount them directly to. Use them to control the speed of air powered equipment by adjusting the volume of airflow. A ball valve has too high of a cv to control properly. Pneumatic flow control and needle valves help you regulate air flow in your compressed air system.

A needle valve features a small port and threaded needle shaped plunger and can allow precise flow regulation at lower flow rates. Choose the inlet and outlet port types in sizes that can fit your application. They control flow in one direction as air moves from the inlet to the outlet. If you want fine control of your air you would use a different valve with a characterized seat like a needle valve.

Flow control valves are essential for optimising system performance and relying on a flow passage or port with a variable flow area. Prevent accidental airflow changes with these valves which require an adjustment tool sold separately to alter their flow rate. Selecting the right flow control valve. Air flows freely in the opposite direction.

Flow control valves are used to reduce the rate of flow in a section of a pneumatic circuit resulting in a slower actuator speed. They create two actions and have two exhaust ports which allows you to control the speed of each action by attaching a flow control valve to each exhaust port. Often used to extend and then retract a cylinder at different speeds they create two actions and have two exhaust ports which allows you to control the speed of each action by attaching a flow control valve to each exhaust port. They re inexpensive and allow basic throttling of the airline.

Since these air piloted flow controls feature an integrated speed controller they offer the best of both worlds in many ways. Unlike a needle valve a flow control valve regulates air flow in only one direction allowing free flow in the opposite direction.
