3A100 Series Pneumatic Valve – Reliable 3/2 Way Air Control Valve

The 3A100 Series pneumatic valve is a 3 port 2 position (3/2 way) air control valve designed to control and distribute compressed air in industrial pneumatic systems. The valve operates through an external air control mechanism, allowing fast and stable switching of airflow direction.

With its compact structure and durable design, this valve is widely used in automation equipment, pneumatic cylinder control, and industrial machinery where reliability and precise airflow control are required.

Key Features

• Sliding column structure provides excellent sealing performance and sensitive response.

• Aluminum alloy body offers strong durability while keeping the valve lightweight and corrosion resistant.

• Low friction internal design ensures low starting pressure and longer service life.

• Memory function for double air control models helps maintain stable operating status.

• No lubrication required, reducing maintenance costs and keeping the pneumatic system clean.

• Manifold mounting capability allows multiple valves to be installed efficiently.
