## Product Summary

PA pneumatic valves are inline flow control valves designed for precise airflow regulation and speed control in pneumatic systems.

With a compact inline structure, PA valves are installed directly between tubes, allowing smooth adjustment of airflow without changing piping direction, making them ideal for linear air circuits and confined installations.

The valve uses a precision needle adjustment mechanism to control air flow rate, enabling accurate actuator speed control and system stability.

Nickel-plated brass material and internal sealing components ensure durability, corrosion resistance, and long service life in industrial environments.

Push-to-connect design enables quick installation and easy adjustment without tools.

OEM and ODM customization services are available for flow range, tube size, and branding.

### Key Features

- Inline structure for straight tube installation

- Precise airflow control with needle adjustment

- Compact design for space-saving installations

- Nickel-plated brass body for durability

- Stable and repeatable flow regulation

- Push-to-connect quick installation

### Applications

Pneumatic automation systemsUsed for controlling cylinder speed and airflow rate

Air circuit controlEnsures stable and adjustable airflow in linear pipelines

Industrial machinerySuitable for actuator speed regulation

Assembly and production linesImproves motion control precision

Compact pneumatic layoutsIdeal for inline installations without direction change

### Product Function

PA pneumatic inline valves are used to regulate airflow and control actuator speed in pneumatic systems.

By adjusting the needle valve, users can precisely control the flow rate, ensuring smooth operation, reduced vibration, and improved system performance.

Compared to elbow or directional speed controllers, PA inline valves are ideal for straight-line installations where airflow direction remains unchanged.
