Pneumatic List

Pneumatics is a branch of engineering that makes use of gas or pressurized air to move parts or perform work.
In simple terms, it is a technology where we compress normal air, send it through pipes, and use that stored energy to push, pull, lift, or rotate machinery.
How a Pneumatic System Works
A complete system works in a continuous loop:
Generation: An air compressor sucks in outside air and squeezes it into a tank (creating potential energy).
Preparation: The air is cleaned and dried (using the FRL Unit you asked about earlier).
Control: Valves direct where the air goes (like the Solenoid Valve).
Actuation: The air pushes a Cylinder to move a load.
Exhaust: The used air is released back into the atmosphere (making the characteristic "hissing" sound).
Why use Pneumatics? (Advantages)
If you are listing products for a website or catalog, these are the key selling points of pneumatic technology:
Safety: Compressed air is not flammable. It is much safer than electricity in explosive environments (like chemical plants).
Simplicity: Components are durable, easy to repair, and have few moving parts.
Cleanliness: If a pipe leaks, it just leaks air—not messy oil like hydraulics. This makes it perfect for Food & Pharma industries.
Reliability: Pneumatic tools can work continuously without overheating.
Pneumatics vs. Hydraulics
Pneumatics uses Air. It is faster, cleaner, but has less force. (Used for packaging, automation, robotics).
Hydraulics uses Oil. It is slower, messier, but has massive force. (Used for cranes, excavators, heavy presses).
Core Product Categories
Based on your previous questions, your "Pneumatic" product range covers the full circuit:
Source/Prep: FRL Units, Fittings, Tubing.
Control: Solenoid Valves, Hand Valves.
Output: Cylinders (Air Muscles).

Pneumatic fittings are the essential connectors used to join sections of pipe, tube, and hose in pressurized gas systems. Compared to hydraulic fittings, they typically require tighter seals and lower pressure ratings.

Common Types of Fittings
The "best" fitting depends on how often you need to change the connection and the pressure of the system.
Push-to-Connect: The most popular choice for modern industrial automation. You simply push the tube into the fitting, and internal "teeth" (a collet) grab it. It’s fast and requires no tools.
Compression Fittings: Use a metal ring (ferrule) that is tightened down by a nut to create a seal. These are better for higher-pressure applications where a plastic push-in might fail.
Threaded Fittings: These have standard screw threads (like NPT or BSP). They are used to connect components like valves or cylinders to the main air line.
Barb Fittings: A plastic or metal "barb" slides inside a flexible hose. A hose clamp is usually required to keep it secure.
Important Considerations
Thread Standards: Make sure you aren't mixing NPT (tapered) with Metric/G (parallel) threads, as they won't seal properly and can damage the equipment.
Pressure Rating: Standard pneumatic systems run between 0 to 150 PSI. Ensure your fitting is rated for at least 20% more than your max system pressure.
Tubing Compatibility: Always match the outside diameter (OD) of your tube to the fitting. For push-to-connect, the tube must have a clean, square cut to prevent leaks.

A Pneumatic ball valve combines a standard quarter-turn ball valve with a pneumatic actuator, allowing for automated control of fluid flow. This setup is highly valued in industrial automation for its durability and fast response times.
Key Components
Ball Valve: The physical mechanism containing a rotary ball with a hole through the center.
Pneumatic Actuator: A device mounted on top of the valve that uses compressed air to rotate the ball.
Mounting Pad: Usually following the ISO 5211 standard to ensure the actuator fits the valve perfectly.
Technical Specifications
1. Valve Body Specifications
Size Range: 1/2" to 12" (Standard industrial sizes).
End Connections: Screwed (NPT/BSP), Flanged (ANSI 150/300, PN16/40), or Triclamp (for hygienic use).
Body Materials: * Stainless Steel (304/316): Best for corrosion resistance.
Carbon Steel (WCB): High-pressure and high-temperature environments.
Cast Iron: General water and air services.
Seat Material: PTFE (Standard), Reinforced PTFE (High pressure), or Metal-to-Metal (High temperature).
2. Actuator Specifications
Operating Media: Filtered compressed air (dry or lubricated).
Air Supply Pressure: 2.5 bar to 8 bar (approx. 40 to 115 PSI).
Type of Action:
Double Acting: Air is used to both open and close the valve.
Single Acting (Spring Return): Air opens the valve, and internal springs automatically close it if air pressure is lost (fail-safe).
Rotation: 90° with ±5° adjustment at both ends.
3. Environmental Ratings
Temperature: Standard actuators operate from -20°C to +80°C.
Protection Class: Often rated IP67 or IP68 for weatherproofing and dust protection.
Common Accessories
Solenoid Valve (5/2 or 3/2 way): Controls the air flow to the actuator via an electrical signal.
Limit Switch Box: Provides remote visual or electrical confirmation of the valve's position (Open/Closed).
Air Filter Regulator: Ensures the air entering the actuator is clean and at the correct pressure.

A Pneumatic butterfly valve is an industrial valve used to control the flow of various mediums (liquid, gas, or slurry) through a pipe. It combines a standard butterfly valve with a pneumatic actuator, which uses compressed air to open, close, or modulate the valve.
How it Works
The valve features a circular disc mounted on a rotating shaft. When the pneumatic actuator receives air pressure, it rotates the shaft, turning the disc.
Fully Open: The disc is parallel to the flow.
Fully Closed: The disc is perpendicular to the flow, sealing against the valve seat.
Key Components
Butterfly Valve Body: The main housing that holds the disc and seat.
Pneumatic Actuator: Mounted on top; can be "Rack and Pinion" or "Scotch Yoke" style.
Solenoid Valve: An electro-pneumatic device that controls the air flow to the actuator.
Limit Switch Box: Provides a signal to the control room indicating if the valve is open or closed.
Positioner (Optional): Used if the valve needs to be partially opened (e.g., 50% flow) rather than just On/Off.
Advantages
Compact Design: Takes up less space than gate or ball valves.
Cost-Effective: Generally more affordable, especially in larger sizes.
Fast Operation: Pneumatic actuation allows for quick opening and closing cycles.
Low Maintenance: Fewer moving parts compared to other valve types.

A Pneumatic solenoid valve is an electromechanically operated valve used to control the flow of compressed air. In industrial automation, these valves are the primary interface between electrical controllers (like a PLC) and pneumatic actuators.
How it Works
The valve contains an internal plunger or spool that is moved by an electromagnetic coil (the solenoid). When an electric current passes through the coil, it creates a magnetic field that pulls the plunger, either opening or closing the internal ports to direct air flow.
Common Configurations
3/2 Way Valve: Has 3 ports and 2 positions. Used to operate single-acting pneumatic cylinders (where a spring returns the cylinder).
5/2 Way Valve: Has 5 ports and 2 positions. Used to operate double-acting pneumatic cylinders (where air is needed for both extension and retraction).
5/3 Way Valve: Similar to 5/2 but includes a "neutral" center position that can lock a cylinder in place or exhaust both sides.
Key Features
Solenoid Coil: The electrical component that triggers the valve.
Armature/Plunger: The moving part that redirects the air.
Manifold Mounting: Often installed on a manifold block to group multiple valves together for easier piping.
LED Indicator: Many connectors include a small light to show when the coil is energized.
Applications
Directly controlling pneumatic cylinders.
Acting as a pilot for larger valves (like the pneumatic butterfly valve).
Air-operated sorting systems and assembly lines.
Packaging machinery.

A pneumatic cylinder is a mechanical device that uses the power of compressed gas to produce a force in a reciprocating linear motion. They are widely used in automation and manufacturing for tasks like lifting, pushing, or pulling.
Common Types of Pneumatic Cylinders
Single-Acting Cylinders (SAC): Use air pressure to move in one direction and a built-in spring to return to the home position. These are ideal for simple tasks like clamping or ejecting parts.
Double-Acting Cylinders (DAC): Use air pressure for both the extend and retract strokes. These are the most common type and are used when the load must be moved in both directions.
Rodless Cylinders: These do not have a piston rod extending outside the cylinder body. Instead, the internal piston is connected to an external carriage via a mechanical or magnetic coupling. They are perfect for long-stroke applications where space is limited.
Compact/Short-Stroke Cylinders: Designed for applications where space is at a premium and only a short stroke is required.
