What is pneumatic flow control valve?

Pneumatic push-in fittings, also called push to connect fittings, provide a leak-free means of easily connecting hoses in your compressed air system. Pneumatic flow control valve is also a pneumatic fitting. Fittings can have between 1-6 inlet/outlet ports or may have additional functionality such as an integrated pressure gauge or silencer.

How to install pneumatic push-in fittings and pneumatic flow control valve?

The hose is easy to install by pushing it into the release ring-end of the fitting until it stops. The internal lock claws will automatically clamp around the hose for an immediate and secure connection.

How to uninstall pneumatic push-in fittings and pneumatic flow control valve?

Push the release ring inward towards the fitting to disengage the lock claws. Similarly pull back on the tubing to remove it. The opposite end may be another push to connect fitting, threaded male, threaded female or a threaded male with an inner hex-type connection. The threaded connections usually have a pre-applied thread lock coating. The tube must be fuller inserted for a proper seal.

The pros and cons of using push-in fittings

Pros

• Push-in fittings come with a quick release system which allows for simple and easy installation by hand. Thereby, eliminating the need for tools and adhesive. Due to the ease of connecting and disconnecting air lines, it allows for frequent changing of air lines at a low cost.
• Push-in fittings are offered in a wide range of tube sizes, connections, and thread combinations to suit the desired outcome.

Cons

• Push-in fittings require firmer tubing with harder walls to resist being damaged by the internal claws. Firm tubing will be less flexible; therefore, it may not be suitable for systems where hoses will be routed around tight turns. If flexible tubing is desired, we recommend using hose tail barbed fittings instead of push-in fittings. Nylon, Polyethylene (PE), or Polyurethane (PU) tubing material is ideal for push-in fittings. It is also best suited for pneumatic (air) applications; however, it can be used for water applications.

Applications

Push-in fittings are used in all types of compressed air systems, but are most commonly used in applications having pneumatic cylinders, tools, and equipment. They can be used for water applications, but extra measures have to be taken (controlled surge pressure, water compatibility, insert ring, etc.) The push on connection method allows for rapid changing of components, so it is ideal if you have one air source for multiple tools that can be exchanged out.

FAQs for Pneumatic Flow Control Valve (Push-In Type for PU Pipe):

• How do I adjust the airflow in a flow control valve for PU pipes?
  Turn the adjustment knob or screw on the flow control valve. This regulates the speed of pneumatic cylinders or tools in your compressed air system, ensuring precise control of air pressure and flow, which improves efficiency and reduces equipment wear.

• Can a flow control valve push-in type be used with multiple PU pipe sizes?
  Yes, the flow control valve push-in type is compatible with a range of PU pipe sizes. Push-in fittings provide a secure, leak-free connection, allowing quick installation and removal without additional tools. Ensure the valve and tubing are properly matched for optimal performance.

• What maintenance is required for a flow control valve in pneumatic systems?
  Regular maintenance includes checking for leaks, ensuring push-in connections are secure, and cleaning any debris from the valve. Proper maintenance ensures smooth airflow, prolongs valve life, and prevents system downtime.

• Why should I choose a push-in type flow control valve over threaded valves?
  A push-in type flow control valve is easier to install and remove than threaded valves, saving time during system changes. It also provides a reliable, leak-free seal for PU pipes, making it ideal for applications requiring frequent adjustments or rapid equipment swaps.
