SU Series Throttle Valve

The SU Series pneumatic speed controller regulates airflow to help achieve smooth, controlled movement in pneumatic cylinders and actuators. Its inline tube-to-tube design connects directly to compatible pneumatic tubing.

Available in five sizes for 4–12 mm tube outer diameters, the SU throttle valve supports unidirectional flow control on either the inlet or exhaust side, depending on system requirements.


SU Series Speed Controllers for Smooth Cylinder Motion

The SU Series pneumatic speed controller helps regulate compressed airflow, allowing operators to fine-tune cylinder movement for more stable operation. Its straight, tube-to-tube configuration connects two sections of pneumatic tubing without requiring a threaded port connection.

Key Features of the SU Throttle Valve

● Adjustable airflow: Fine-tunes the flow rate to control actuator speed.

● One-way control: Supports inlet-side or exhaust-side throttling according to the installation direction.

● Multiple tube sizes: Available for 4, 6, 8, 10, and 12 mm tube outer diameters.

● Inline connection: Provides a straightforward option for pneumatic piping layouts.

Where the SU Series Is Used

SU Series speed controllers are suitable for pneumatic cylinders, automated assembly equipment, packaging machinery, and other systems that require controlled actuator movement.

Installation and Size Selection

● Match the SU model to the tubing outer diameter.

● Connect the two tubes securely to the push-in ports.

● Install the valve in the correct direction for the intended inlet or exhaust flow control.

● Adjust the throttle gradually and test cylinder movement before normal operation.
