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.
Air flow control valves.
Pneumatic flow control and needle valves help you regulate air flow in your compressed air system.
Flow control valves are used to reduce the rate of flow in a section of a pneumatic circuit resulting in a slower actuator speed.
Use them to control the speed of air powered equipment by adjusting the volume of airflow.
Since these air piloted flow controls feature an integrated speed controller they offer the best of both worlds in many ways.
Valve type inline female thread size 1 4 minimum psi 0 0 maximum working pressure psi 140 78 type flow control material aluminum alloy view product aro ingersoll rand 1 8 male npt.
They ship with an integrated pilot check valve as well as a temporary intermediate stop dial.
Air flows freely in the opposite direction.
Selecting the right flow control valve.
These valves close all ports in the off position to stop equipment in a locked position with air pressure holding it in place.
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.
A needle valve features a small port and threaded needle shaped plunger and can allow precise flow regulation at lower flow rates.
That being said most people won t need that tight control and these valves work great.
Also known as 4 way and 5 3 closed center valves.
Choose the inlet and outlet port types in sizes that can fit your application.
They control the speed of air powered equipment by adjusting the volume of airflow.
Flow control valves are essential for optimising system performance and relying on a flow passage or port with a variable flow area.
The range includes pneumatic and hydraulic control valves which are designed to cope with high flow rate working pressure and can be used for a variety of.
Parker flow control valves are designed to regulate the flow rate and pressure of media through a pipeline.
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.
Unlike a needle valve a flow control valve regulates air flow in only one direction allowing free flow in the opposite direction.
This makes independent speed control of different cylinders a breeze.
They re inexpensive and allow basic throttling of the airline.
Air piloted flow controls.
These valves close all ports in the off position to stop equipment in a locked position with air pressure holding it in place.
Prevent accidental airflow changes with these valves which require an adjustment tool sold separately to alter their flow rate.
